Chapter VIII: Part 8
On Plate 81 are shown three examples of this variable species. Fig. 10 represents the typical form from N. Devon. Fig. 11 is a black-marked specimen from Yorkshire, and Fig. 12 depicts a smoky-brown marked specimen from Clydesdale, in which the ground colour has a brownish tinge. All these have the central band more or less entire, but this character may be broader or narrower, and is sometimes divided into two parts, and these reduced to very small proportions; the white projections into {199} the outer marginal border of all the wings is not infrequently enlarged, in some cases so much so that the borders are separated into two parts, and also reduced in width.
The caterpillar is grey brown, ochreous brown between the rings and on the underside; a dark line along the back, and a dark-edged, pale line on each side; a black dot on each ring at the junction of the dark upper and pale lower areas; head, grey-brown, with blackish freckles. It feeds, in July and August, on bedstraw, preferring the heath kind (_Galium saxatile_), but will eat the large hedge kind (_G. mollugo_).
The moth is out in June, or from late May, and in some parts specimens are seen in August. Its haunts are moors and upland heaths, and its British distribution extends from Dartmoor and Exmoor, in Devon, through Western England and Wales to Westmorland. It appears to be very local in Somerset, Gloucester, Hereford, Shropshire, and Cheshire; from Staffordshire and Derbyshire northwards, and through Scotland, it becomes more plentiful; and has been recorded from the Shetlands. In Ireland it is local, but common where it occurs.
SHARP-ANGLED CARPET (_Xanthorhoe_ (_Euphyia_) _unangulata_).
This species (Plate 82, Figs. 1, 2) may be recognized by the distinctly angled outer edge of the blackish central band, which is thrown into strong relief by the usually broad white stripe following it. Wilkes, who figured the moth in 1742, called it the "White Stripe." By some authors the species is referred to _amniculata_, Hubner.
The caterpillar is pale whity brown, with a slightly darker but indistinct line along the centre of the back, and a black spot on the middle rings; a pale line on the sides is edged with dark grey; head, brown, marked with black. It feeds, in July and early August, on chickweed (_Stellaria media_).
The moth, which is partial to hedges and easily disturbed {200} therefrom, is out in June and July, and even later in some seasons. The earliest hatched caterpillars reared in confinement sometimes attain the moth state in August of the same year. Although certainly local, the species has a wide distribution in the southern half of England, and is not uncommon in some localities. Its range extends into Wales, and also northwards to Cumberland and Westmorland, but it is generally very much scarcer in the north than in the south. In Ireland it is known to occur locally in counties Antrim, Tyrone, Fermanagh, Waterford, Kerry, and Galway, but, as a rule, only sparingly.
Abroad, the distribution includes North Amurland and North America.
CLOAKED CARPET (_Euphyia picata_).
An older English name for this species (Plate 82, Figs. 4, 5) is "The Short Cloak Carpet," Harris (1782), but that given to it by Haworth is here adopted. It is also the _biangulata_ of Haworth, Stephens, and others.
As will be observed on referring to the figures, the outer edge of the blackish central band of the fore wings is twice angled just above the middle; the basal area and the outer marginal border are dark greyish brown, more or less tinged with olive; the whitish ground colour only shows distinctly as a strip immediately beyond the central band, and from this an irregular streak runs to the tips of the wings; some white wavy cross-lines through the outer border are often obscure.
The stoutish caterpillar is yellowish brown, or sometimes reddish brown; there is a series of blackish or dark-brown spots along the back, and a stripe of dusky freckles along each side; lower down are two slender wavy lines enclosing a dusky stripe; head, yellowish-brown mottled with darker brown. It feeds, at night, on chickweed and other kinds of _Stellaria_, in {201} August and September. One of the mouse-ear chickweeds (_Cerastium glomeratum_) has also been mentioned as a food plant, and for rearing the caterpillars this would perhaps be useful, as common chickweed, unless in a growing state, is difficult to keep in a suitable condition for larval requirements.
The moth, which is partial to a hedgerow as a hiding-place, is out in June and July, and may be sometimes reared as a second generation in September.
The species is somewhat local, but it is not scarce in many parts of England; its range does not appear to extend northwards beyond Worcestershire on the western side, although it has been recorded from North Wales; on the eastern side it is found up to Norfolk.
THE ARGENT AND SABLE (_Eulype hastata_).
About one hundred and sixty years ago Wilkes figured this species as "The Mottled Beauty," but Harris in 1778 gave it its present English name. On Plate 82 are shown two examples of the typical form (Figs. 7, 8), also two specimens of the small form (Figs. 10, 11), var. _subhastata_, Nolcken (= _hastulata_, Hubner); the latter form in Britain occurs chiefly in Sutherlandshire and the Isle of Lewis. As regards variation there is, in the small form, a tendency to an increase of black; whilst in the typical form there is a considerable reduction of the black marking--so much so occasionally that of the central black band only a few dots remain around the discal spot, and perhaps a speck or two below it, and a dot or two on the inner margin (ab. _demolita_, Prout).
The rather stumpy caterpillar is dark olive-green, inclining to blackish, and somewhat shiny; the skin along the sides puckered and marked with ochreous; a black line along the middle of the back; head, black and glossy. It feeds, in July and August, later in the north, on birch, _Vaccinium_, chiefly {202} _uliginosum_, and sweet gale (_Myrica_). It spins together the leaves at the tips of the twigs, and so forms a cocoon-like habitation. The moth is out in May and June, and even July in the north. It flies in the afternoon sunshine around and over birch trees, and occasionally alights on the leaves. It has been taken in Kent, and more frequently in Essex and Suffolk, but it is more plentiful in Oxfordshire and Berkshire, and from Surrey to Dorsetshire and Wiltshire; also in Herefordshire and Worcestershire, and on high ground in North Wales, Staffordshire, and Derbyshire; its range extending through Cheshire and Lancashire to Cumberland and Northumberland, but only odd specimens have been reported from the last-named county and from Durham. The egg and the caterpillar are shown on Plate 79, Figs. 1 and 1a.
It is widely distributed, and often common in places, throughout Scotland. In Ireland it is local, but has occurred plentifully in some of its haunts in that country; Kane states that var. _subhastata_ has not been noted.
The range abroad spreads to Amurland, China, Iceland, Labrador, and North America.
BEAUTIFUL CARPET (_Mesoleuca albicillata_).
The English name of this species (Plate 82, Fig. 13) is exceedingly appropriate; few of our native moths exhibit such a pleasing combination of colour and marking. It varies but very little in a general way, but a specimen taken in York some years ago has the fore wings dark leaden grey instead of creamy white (ab. _suffusa_, Carrington), and very rarely the ground colour inclines to yellow.
The stoutish caterpillar (Plate 76, Fig. 2) is green with reddish marks along the back; a white line low down along the sides is edged below with purplish red on the first three rings; the last ring, and the claspers, tinged with purplish red. It feeds {203} at night on bramble and raspberry, in August and September, occasionally earlier or later. In the daytime it rests on the underside of a leaf. When full grown it forms a cocoon just under the surface of the soil, or among rubbish (in the cage), and therein changes to a dark reddish-brown chrysalis (Plate 76, Fig. 2a).
The moth is out in June, sometimes in late May, and occasionally there seems to be a few individuals about in August. The species is a denizen of the woodlands, and is generally to be found in the more open parts of woods where its food plants are well established. It is widely distributed over England and Wales, but most frequent in the south of the former country. In Scotland, it is local in Roxburghshire and Wigtownshire; and it occurs in many parts of Ireland. The range abroad extends to Amurland and Japan.
THE PURPLE BAR (_Mesoleuca ocellata_).
The whitish fore wings of this species (Plate 82, Fig. 12) are often tinged with pale ochreous brown on the lower two-thirds of the outer marginal area, and this tint sometimes invades the central portion of the bluish-black central band. Rarely the ground colour is almost entirely white, and the central band is very slender (ab. _coarctata_, Prout), and perhaps rather more frequently the band is completely severed below the middle.
The caterpillar, which feeds at night on bedstraw (_Galium mollugo_ and _G. verum_), is pale ochreous brown, or pale pinkish brown, netted with darker brown; on the back are a reddish ochreous central line, and some reddish edged pale V-marks: June and July, and sometimes again in the autumn.
The moth is out in June and early July, occasionally in late May in some southern localities. Individuals of a second emergence sometimes appear in August and September. It {204} rests by day on tree-trunks or in hedges, and flies at night. Widely distributed over the British Isles, but, except perhaps in the highlands of Scotland, not very common.
BLUE-BORDERED CARPET (_Mesoleuca bicolorata_).
The more usual form of this pretty little species is shown on Plate 82, Figs. 3 and 6. In the type the central band is only represented by a spot on the front margin of the fore wings; in ab._parvula_, Retz = _rubiginata_, Hubner, there is also a portion of the band showing on the inner margin. Ab. _plumbata_, Curtis, from Scotland has the central band entire and the ground colour inclining to creamy white. In ab. _fumosa_, Prout, the usual white parts of the wing are smoky or dark lead colour (Fig. 9). Barrett mentions a form with all the wings smoothly smoky black; markings of the fore wings olive brown, margined with slender stripes of smoky white.
The long, thin, caterpillar is green, with a darker stripe along the back, and a yellowish green stripe on each side; two points on the last ring. It feeds on alder, birch, sloe, and crab; also in orchards and gardens on plum and apple: April to June.
The moth is out in July and August. It appears to occur most freely in districts where alder is plentiful, but it is not uncommon in country lanes, especially where these are rather moist. It is one of the earliest Geometrid moths to get on the wing, as it is generally active well before dark. Decidedly more common in some districts than in others, but it may be said to be generally distributed.
The range abroad extends to Eastern Siberia, Amurland, and Japan, but the ab._fumosa_ is only known from Britain.
PRETTY CHALK CARPET (_Melanthia procellata_).
From almost any well-grown hedgerow, in which traveller's joy, or old-man's beard (_Clematis vitalba_) is plentiful, throughout the southern counties of England, this species (Plate 82, Fig. 14) may be disturbed by the beating stick. It is generally to be met with in July and early August, but may be obtained in forward seasons, or in sheltered localities, at the end of June.

{205} On the fore wings the dark, slender and wavy cross lines are more distinct in some specimens than in others, and occasionally the blackish blotch on the front margin is traversed by a white line, sometimes by two lines.
The caterpillar is pale ochreous brown, with three darker brown lines along the back, the central one slender, spotted with black on the middle rings; usual dots, black, encircled with white; head, marked with a reddish brown triangle. It feeds on _Clematis_ in August and September.
Distribution of the species abroad extends to Amurland, and in Japan, Corea, and China it is represented by the darker _inquinata_, Butler.
THE RIVULET (_Perizoma affinitata_).
The whitish band crossing the brownish fore wings is generally fairly wide, sometimes broad, but occasionally it is very narrow; the reduction in width is mainly the result of brownish suffusion of the outer half of the band, leaving the inner half white. Kane mentions a smoky form from Co. Derry, in which the band is absent, and refers this to ab. _unicolorata_, Gregson. In a specimen from Sligo in my series, the band is tinged with brownish throughout. The hind wings are usually smoky brown, with a paler central band, but in some specimens, referable to ab. _turbaria_, Stephens, the basal two-thirds are whitish. The moths also vary in size (Plate 83, Figs. 1 and 2).
The caterpillar is pinkish-ochreous inclining to brown; three pinkish lines along the back, and a similar line along the blackish spiracles; a dark plate on the first and last rings. It feeds in the capsules, on the seeds, of red campion (_Lychnis_ {206} _dioica_), and will eat those of the white _L. vespertina_: July to September. When eggs can be obtained early, it is possible to rear moths from them in August of the same year.
The moth is out in June and July, in some southern districts in late May.
As it conceals itself during the day among its food plant, or other vegetation around, it may be put up therefrom by gently stirring the herbage; but it flies freely about sundown, and is then easily netted.
The species is widely distributed over England, Wales, and Scotland, up to Moray. In Ireland it is local and not plentiful, and the same is the case in the North of England.
SMALL RIVULET (_Perizoma alchemillata_).
This species (Plate 83, Figs. 3 and 6) is exceedingly close to the last mentioned, but in a general way it is to be distinguished by its greyish-brown coloration. A stippled whitish stripe before the central band, usually only faintly indicated in _affinitata_, is fairly distinct as a rule. Although the outer edge of the central band is rather more irregular, the middle tooth is not so prominent as in _affinitata_.
The rather plump caterpillar is purplish above and yellowish green below; three yellow lines on the back, the central one broad; the spiracles are black, and a little above them is another yellow line; head, black and glossy, and there are black shining plates on the first and last rings of the body, that on the first ring divided by the yellow central line (adapted from Porritt). It feeds, in August and September, in the seed capsules of hemp nettle (_Galeopsis tetrahit_), sometimes on the rarer _G. ladanum_, and is said to eat woundwort (_Stachys_) occasionally.
The moth is out in June and July, and, as in the case of the last species, may be stirred up from among its food plant or the surrounding vegetation, in lanes, and around wood borders. The species is widely distributed over the British Isles, except that it seems not to have been noticed in Scotland, north of Moray, although it occurs in the Hebrides.

{207}
SANDY CARPET (_Perizoma flavofasciata_).
The pale ochreous-brown, or sandy, markings on the white fore wings of this species readily distinguish it from either of its allies. Variable in size, and also in the brownish tint of the markings; the central band is usually contracted below the middle, and not infrequently it is completely severed at this point. It is the _decolorata_ of Hubner, and although more generally known by that name, the earlier _flavofasciata_, Thunberg, will have to be adopted for this species. (Plate 85, Figs. 1 [male], 2 [female].)
The stoutish caterpillar is pale reddish ochreous with browner lines; head, brown and shining, plate on first and last rings of the body brown. It feeds on the flower buds, and on the immature seeds, of the red campion (_Lychnis dioica_), and the white campion (_L. vespertina_), but is more partial to the first named; in Ireland it is said to feed on bladder campion (_Silene inflata_).
In July and August, or even later, the moth may be beaten out of hedgerows, sandy banks, and borders of woods, and sometimes disturbed from patches of the campion growing in thickets; in such places it is on the wing about sundown.
Although local to some extent, it appears to be common enough in most of the counties of England and Wales. In Scotland, it is more or less generally common in Roxburghshire and Clydesdale, and is said to have been an inhabitant of Perthshire (Moncrieffe Hill). It appears to be very local in Ireland, but is recorded from Antrim, Derry, and Kerry, and noted as common at Larne in the first-named county. {208}
GRASS RIVULET (_Perizoma albulata_).
Although some English specimens approach the larger and whiter typical form, the species as it occurs in the British Isles is generally greyer, var. _griseata_, Staudinger; two examples of this form are shown on Plate 83, Figs. 10 and 11. In the Shetland Isles, the species assumes a darker coloration, and is either well marked on the fore wings, as in Fig. 14, or almost plain, as in Fig. 13 (ab. _thules_, Weir), which is an extreme aberration of the form _subfasciaria_, Boheman. In other examples of a deep leaden grey, or brown tint, the central area is no darker than the rest of the wing. In the Isle of Lewis a white form with faint markings is prevalent, and this leads up to a clear white aberration devoid of markings, ab. _niveata_, Stephens, = _hebudium_, Weir.
The wrinkled caterpillar, which feeds, in July and August, on the seeds of the yellow rattle (_Rhinanthus crista-galli_), and lives in the capsule, is whitish, inclining to greenish, dotted with black, and striped with dark green on the back and sides; head, black and glossy; plates and first and last rings of the body dusky. (Plate 84, Fig. 1.)
The moth is out in May and June, sometimes later. It occurs chiefly in dry meadows where the yellow rattle flourishes, and is to be seen on the wing, often in large numbers, in the late afternoon about sundown. Generally abundant in suitable places, throughout the British Isles.
THE BARRED RIVULET (_Perizoma bifasciata_).
Haworth described two forms of this species, and a specimen of each is shown on our Plate 83. Fig. 4 represents _bifasciata_ (_bifaciata_, the Double-barred Rivulet), and Fig. 5 depicts {209} _unifasciata_ (the Single-barred Rivulet). The chief difference appears to be that in the type (_bifasciata_) the "rivulets" are white and distinct, thus bringing out a dark band between the central one and the base of the wing.
The stoutish caterpillar is pale brown, inclining to ochreous on the back, along which are three lines, the central one greyish, and the others whitish shaded with greyish; a whitish stripe low down along the sides; the usual dots are black, and the spiracles are black, margined with ochreous (adapted from Fenn). In September and October it feeds in the seed capsules of _Bartsia odontites_, and is often plentiful; Mr. G. F. Mathew records obtaining nearly five hundred from three small bundles of the food plant gathered in the Harwich district.
The moth is out in July and August, but is not often seen in the daytime, and is not taken very frequently, even when flying at night, but it comes to light, and visits flowers.
From chrysalids obtained from caterpillars reared in 1900, Mr. Robert Adkin bred ten moths in 1901, eleven in 1902, two in 1903, five in 1904, and two in 1905.
The species is widely distributed over England, Wales, and the south of Scotland, but it is most frequent in the south of England. Not much is known of it in Ireland, but it has been noted from counties Dublin, Louth, and Derry.
HEATH RIVULET (_Perizoma minorata_).
The British form of this species (Plate 83, Figs. 9, 12) is rather smaller and darker than typical _minorata_, Treitschke, and as Stephens has figured and described it as _ericetata_, this name should be adopted for our native race.
The white fore wings have a greyish basal patch and three bands of the same colour; the outer one is traversed by a more or less distinct wavy whitish line; the band nearest the basal patch is sometimes very faint; more rarely the markings are {210} absent from the central area of the wings (ab. _monticola_, Staud.), and a specimen approaching this form has been taken in Perthshire.
The caterpillar is pale green with a dark-green edged ochreous brown stripe along the middle of the back, and green stripes on each side; the usual dots are black, and the plates on first and last rings are brown, as also is the head. It feeds, in September, on the seeds of eyebright (_Euphrasia officinalis_).
The moth is out in July and August, and is found very locally, flying in the late afternoon among its food plant, on the moorlands and pasture-grounds of Northumberland, Cumberland, Durham, and Westmorland; and has been reported from Hawkshead, in Lancashire. In Scotland, it is common in suitable parts of Roxburghshire and several localities in Clydesdale; thence widely spread to the Orkneys. Only noted from the Mourne Mountains in the north-east of Ireland, but probably to be found in other parts of that country.
PRETTY PINION (_Perizoma blandiata_).
This species (Plate 83, Figs. 7, 8) is also known as _adaequata_, Borkhausen, the name under which it is catalogued by Staudinger. As a rule the central band on the whitish fore wings is only represented by a round, or sometimes triangular, blackish spot on the front margin, a smaller blackish mark on the inner margin, and some dusky clouding between these two portions. In specimens from the Hebrides the band is more or less complete, and in some of them it is very much narrowed, especially towards the inner margin (ab. _coarctata_, Prout).
The caterpillar is green, with three crimson lines, the outer ones bent inwards to the central one on the middle of each ring; two lines above and one below the yellowish spiracular line are pink; head green, tinged and freckled with pink. It {211} feeds in September on the flowers and seeds of the eyebright (_Euphrasia officinalis_).
The moth is out from late May to July, and its habits are similar to those of the last species. In Scotland it appears to be commoner than in other parts of the British Isles, its range extending from Clydesdale to the Hebrides, Orkneys, and Shetland; but it has been recorded from Cumberland, and once from Durham. In Wales it has been taken at Dolgelly, in Merionethshire. Prout states that in 1902 he secured two specimens near Cwm Bychan, and that the species has since been captured regularly in the locality. It is widely distributed throughout Kerry and Galway, and also recorded from Cork and Derry, in Ireland.
THE BARRED CARPET (_Perizoma taeniata_).
This species is shown on Plate 85, Fig. 3. There are two forms of the central band of the fore wings, which in the type as figured by Stephens is broad, but is narrow in ab. _arctaria_, Herrich-Schaeffer = _angustifasciata_, Staud. The colour of the bands may be greyer or browner than in the specimen figured, and the ochreous general colour of the fore wings is more tinged with brown in some specimens than in others.
The rather bristly caterpillar is light brown with a pinkish tinge; the back is marked with browner diamonds and some black dots, and there is a yellow stripe along the sides. It feeds on moss (Hodgkinson, _Entom._ xxviii. 241) growing in damp places, hibernates when quite small, and reappears about April, when it seems to prefer the fruit of the moss, but will also thrive on chickweed. The moths appear from the end of June, and may be found, but in wasted condition, up to early September.
The species is extremely local, and in its secluded haunts may be found on the trunks of holly and yew trees, or it may {212} be disturbed from the branches of such trees, or from hedgerows, etc.
In Britain the species seems to have been first noted in Castle Eden Dene, Durham (1825), and subsequently in Cumberland (Flimby, near Maryport), Westmorland, Lancashire (Arnside and Silverdale), Yorkshire (Scarborough), Derbyshire (Dovedale), Arthog in North Wales, and Tintern in Monmouthshire. The only English locality for it south of Monmouth is Watersmeet, near Lynton, in North Devon. In Scotland, it has been noted from Rannoch and Pitlochrie, in Perthshire, and from Dalmallin, in Argyllshire. It has a wide distribution in Ireland, and is common in some parts of that country, as at Killarney, Co. Kerry, and Rockwood, in Sligo.
Abroad, the range extends to Amurland; it is represented in Japan by _fulvida_, Butler, and in North America by _basaliata_, Walker.
YELLOW SHELL (_Camptogramma bilineata_).
This very common and generally distributed species is subject to a good deal of variation in the tint of ground colour, and also in the greater or lesser amount of black marking. On Plate 85 six specimens are shown; Figs. 4, 5 represent the more frequent form in most localities, but in many districts ab. _infuscata_, Gumppenberg (Fig. 6), is hardly less common; in some specimens the central band is entirely blackish, and occasionally the middle area of the band is partly or wholly whitish. Sometimes the wings are uniformly yellow without markings, but such aberrations are scarce, or have not been noted often. A small form occurring in the Hebrides and the Shetlands, var. _atlantica_, Staud., has the wings generally darkened; Figs. 7-9 depict three specimens from the Isle of Lewis. Portraits of two very local Irish forms will be found on Plate 61; one is ab. _hibernica_, Prout (Fig. 5), and the other approaches the dark ab. _isolata_, Kane (Fig. 6).

1. JULY HIGHFLYER: _eggs and caterpillars_.
2. MAY HIGHFLYER: _caterpillar_.
{213} The eggs, which are laid loosely, are yellowish or pale straw colour (Plate 84, Fig. 3a). Caterpillar, stoutish, green inclining to yellowish; three lines on the back, the central one dark green, and the others yellowish, as also are the ring divisions; a pale wavy line low down along the sides. In some examples the general colour is pale greyish-brown, inclining to reddish brown. It feeds on grass, dock, chickweed, and various low-growing plants, from August to May, and is often abundant in hay meadows (Fig. 3, Plate 84, is from a coloured drawing by Mr. A. Sich). The moth occurs throughout the summer, and is very plentiful (often a pest) in almost every hedgerow and most bushy places.
JULY HIGHFLYER (_Hydriomena furcata_).
Some idea of the variable character of this species (_sordidata_, Fab., and _elutata_, Hubner) may be formed from the selection of half a dozen examples shown on Plate 86. The typical form has the fore wings greyish, with dark bands as in Fig. 1, and a modification without the dark bands seems to be ab. _cinereata_, Prout. In the form _sordidata_, Fabricius, the general colour of the fore wings is greenish, and the bands are dark; ab. _obliterata_, Prout, is of the same colour, but the bands are absent. Ab. _fusco-undata_, Donovan, has the general colour reddish, with dark bands; without dark bands it becomes _testaceata_, Prout. Blackish or sooty forms are referable to _infuscata_, Staud. (Fig. 4). Frequently in the green forms, and less often in the reddish, there is a broad whitish central stripe, and a narrow one on the basal area; in the green form again the basal and central areas are occasionally crossed by red bands, and this is one of the prettiest forms of the species and, so far as I know, occurs only in the large sallow-feeding race; {214} it possibly represents ab. _fusco-undata_, which is most frequent in the smaller moorland race.
The egg (Plate 87, Fig. 1b) when figured, February 8, 1908, was whitish as regards the shell, but the interior was dark greenish. In April the caterpillar appeared to be formed, but it did not leave the shell until early in May.
The full-grown caterpillar (Plate 87, Figs. 1, 1a) is brownish, inclining to blackish; whitish between the rings, white lines along the back and sides, and tinged with red along the spiracular region. It feeds, in May and June, on sallow, willow, poplar, hazel, bilberry, and heather. The moth is out in July and August, but I have seen the small bilberry-feeding form (Plate 86, Figs. 5, 6) on a corner of Exmoor, North Devon, in great profusion in late June, whilst in the same district the sallow-feeding, larger form appeared about a fortnight later, at which time specimens among bilberry were not numerous, and rather shabby in appearance.
Except perhaps in the Shetlands, this species is to be found in all parts of the British Isles. It is very common in hedgerows, and around the margins of woods; the smaller race frequents woods where bilberry is established, and also occurs on mountains and moors.
Abroad, the range extends to Amurland, China, Japan, and also to North America.
MAY HIGHFLYER (_Hydriomena impluviata_).
The typical and commoner form of this species is shown on Plate 86, Figs. 7 and 8. The ground colour, usually pale green, is sometimes almost white, but more frequently it is tinged with greyish brown, thus leading up to the blackish ab. _infuscata_, Prout (Figs. 9, 10).

1, 1a. SHOULDER-STRIPE: _caterpillar and chrysalis_.
2, 2a. STREAMER: _eggs and caterpillars_.
{215} The caterpillar is brownish grey, or purplish grey, dotted with black and dappled with dark brown; of the three lines along the back, the central one is black and swells out on the middle of each ring, the others are pale; a clear stripe of the ground colour below the black spiracles, and a slender line above them. The general colour is sometimes pale pinky brown or ochreous. It feeds on alder throughout the summer and autumn, and may be found in its domicile of spun-together dry leaves even in November, and sometimes later. Occasionally, a few caterpillars will feed up quickly, and attain the moth state in July or August, but the bulk do not become chrysalids until later in the year, and the moths emerge therefrom in May and early June. (Plate 87, Fig. 2.)
The species seems to occur, more or less freely, wherever there are alders throughout the greater part of the British Isles.
Abroad, the range extends to Eastern Siberia and Amurland.
RUDDY HIGHFLYER (_Hydriomena ruberata_).
This species is most readily distinguished from the last by the short oblique black streak on the tips of the rather narrower fore wings; there are also black streaks between the veins and below the tips of the wings, as in the last species, but they are generally shorter and often hardly traceable.
The ground colour ranges from pale grey (sometimes with a green tinge), through brownish grey to reddish brown; usually central and outer marginal bands of a darker shade are present, but these characters may be very indistinct or entirely lost in the general coloration. (Plate 86, Figs. 11 and 12.)
The caterpillar is pale brown, dappled with grey; three dark greyish lines along the back; spiracles and the usual dots black, the latter with fine hairs; head, reddish brown, plates on first and last rings of the body light brown. It feeds, at night, during the summer and autumn, on sallow and willow, spinning together the leaves at the top of a twig to form a retreat during the day. {216}
The moth is found in hedges, woods, and on heaths, in May and June; it may be occasionally beaten out of sallow bushes, but flies in the early evening, and is then more readily obtained. The species is widely distributed, but not generally common, in England and Wales, and in Scotland to Perthshire and probably further north, as it is found in Orkney, where specimens are numerous but rather small in size, and the caterpillars, according to McArthur, feed on heather as well as on sallow. Decidedly uncommon in Ireland, but it has been met with, in most instances singly, in Armagh, Tyrone, Westmeath, Kerry, Galway, and Sligo.
ROYAL MANTLE (_Anticlea cucullata_).
This species (Plate 88, Fig. 1) is also known as _sinuata_, Hubner. The white fore wings have a blackish patch at the base and a blackish mark on the front margins beyond the middle; the former is separated into two parts by a pale reddish-brown band, and there is a reddish band, most distinct on the front area, beyond the black mark; in some specimens these bands are greyish.
The caterpillar is green, sometimes inclining to yellowish, with two black or purplish stripes, enclosing a broader pale yellow one, along the back; head, green, freckled with black. It feeds on the flowers of bedstraw (_Galium mollugo_, and _G. verum_), in July and August, or later in some seasons.
The moth is out in late June and in July, and occasionally may be disturbed from its food plant or the surrounding herbage. About dusk it is on the wing, and later is attracted by light. It seems to occur in most of the English counties from Kent to Cornwall; also in Berks., Oxon., Herts, and the eastern counties. Always local, and except in the east, where it is found in the Breck-sand area, most frequent in chalky localities. Barrett notes a specimen from Knowle, Warwickshire, and there are at {217} least two records from Scotland (Perthshire). In Ireland, Mr. W. F. de V. Kane took one example from a wall in co. Clare, and another has been recorded from Galway.
The range of the species abroad extends to Siberia and Amurland; and it is represented in Corea and Japan by _A. yokohamae_, Butler.
THE SHOULDER STRIPE (_Anticlea badiata_).
The ground colour of the fore wings is pale ochreous brown, inclining to whitish; there are three dark-edged black cross-lines, the first of them sharply bent below the front margin, the second is rather oblique, and the third is wavy and often not clearly defined towards the inner margin; the outer marginal area is broadly bordered with pale reddish brown or dark purplish brown, there is a black streak from the more or less indistinct, whitish submarginal line to the tips of the wings, and a white mark about the middle of the line; the ground colour is most in evidence on the central area of the wings, but even here it is frequently reduced to a slender band, or occasionally only a patch near the front margin of the wing. (Plate 88, Figs. 2-4.)
The caterpillar (Plate 89, Fig. 1) is green, inclining to yellow between the rings; the spiracles are black, and there is sometimes a pinkish brown or purplish stripe along their area. Varies in general colour, and also in marking. It feeds, at night, on wild rose, and may be beaten from the bushes from May to July. When full grown it forms an oval cocoon in the earth, and therein changes to a chrysalis (Plate 89, Fig. 1a), which is dark reddish brown, inclining to blackish on the thorax, wing-cases, and the front edges of the body rings.
The moth appears in March and April, and may be obtained from almost any hedgerow, where wild rose is plentiful, throughout the British Isles, except that it seems not to extend north of Moray in Scotland. {218}
BARBERRY CARPET (_Anticlea berberata_).
The fore wings are greyish or whitish, tinged with grey; there are two dark-edged black lines on the basal half, and a black line beyond the middle of the wings; the latter has a conspicuous tooth in its upper half, but the lower wavy half is indistinct; there is a black streak in the tip of the wing. (Plate 88, Figs. 5, 6.)
The stout and roughened caterpillar is brown, with indistinct darker stripes along the back; the head is brown, checkered with darker brown. It feeds, in June and July, on barberry (_Berberis vulgaris_); there is a second brood in late August and September.
The moth is out in May and early June, and again in August. Although it certainly has been noted from other parts of England, the species seems at present to be confined to the eastern counties. Barrett gives Somerset also.
THE FLAME (_Anticlea rubidata_).
The markings on the reddish fore wings of this species (Plate 88, Figs. 9 and 10) are somewhat similar to those of the last mentioned, but there is no black streak in the tips of the wings, and the upper part of the outer black line is not toothed. The lower central area is often greyish, and the reddish ground colour is sometimes obscured.
The caterpillar is pale brown, sometimes greyish or greenish tinged, with obscure darker diamond-shaped marks on the back; a black central line, indistinct on the middle rings; under side striped and lined with pale and dark brown; head, with a black V-shaped mark. It feeds, in July and early August, on bedstraw (_Galium mollugo_ and _G. verum_), and will eat cleavers or goosegrass (_G. aparine_) in confinement.

{219}
The moth flies in June and July, and in the daytime may be readily disturbed from hedges in localities on the chalk in the southern half of England and Wales, especially in the seaboard counties from Kent to Cornwall. It has been recorded from Derbyshire and Yorkshire, and once from the Isle of Arran (_Entom._ xv. 250).
THE STREAMER (_Anticlea nigrofasciaria_).
The two examples of this species depicted on Plate 88 show the ordinary form with the central area of the fore wings greyish brown (Fig. 7, Essex), and a New Forest specimen in which the central area is whitish (Fig. 8).
The long caterpillar is green, inclining to yellowish between the rings; a purplish, or reddish-brown, stripe along the back is broken up into spots on the middle rings. It feeds on the flowers and leaves of wild rose, and can be found or beaten out in May and June. (Plate 89, Figs. 2, larva, 2a, ova.)
The moth is out in April and early May, and is often seen at rest on palings, etc., but it occurs chiefly in hedgerows, along which it flies at dusk.
This species (also known as _derivata_, Borkhausen) is pretty well distributed over England, Wales, and Scotland up to Sutherlandshire. In Ireland it seems to be local.
DINGY SHELL (_Euchoeca obliterata_).
This pale ochreous brown species (Plate 91) is in the male (Fig. 1) more or less sprinkled and shaded with darker brown, and the three brown cross lines are consequently often obscure, and rarely as distinct as in the female (Fig. 3).
The green caterpillar has a yellow line running down the middle of a black stripe along the back, and this stripe is {220} bordered on each side with yellow, and broken up by the yellow ring divisions; head, with a black spot on each side. It feeds, in July and August, on alder.
The moth is out in June and early July, and will be found in almost every locality in England where the alder flourishes, most plentifully, perhaps, on the eastern and western sides. It has been recorded from North and South Wales, but it does not seem to have been noted from Ireland or Scotland.
The range abroad extends to Amurland and Japan.
SMALL WHITE WAVE (_Asthena candidata_).
The delicately lined white moth shown on Plate 91, Figs. 5 [male] and 6 [female], is chiefly a woodland species. It is generally common in the south of England, occurs more or less frequently throughout the northern half, and is widely distributed in Wales. In Scotland, it is said to be locally common in Clydesdale, and to be found in Arran and in Perthshire. It is plentiful at Dromoland, co. Clare, Ireland, not uncommon in parts of Galway, and once recorded from Wicklow.
The caterpillar is found, in July and August, on birch, hazel, and wild rose. In general colour it is green, inclining to bluish at each end, and tinged with yellowish along the ridge on the sides; the back is marked with crimson. (Plate 90, Fig. 2, after Hofmann.)
The moth is out in May and June, and sometimes July, and individuals of a second generation occasionally appear in August or September.
SMALL YELLOW WAVE (_Asthena luteata_).
This pretty little species (Plate 91, Figs. 2 and 4) has the pale yellowish wings marked with ochreous brown lines, which vary in thickness, and a dash of the same colour on the fore wings, from the central pair of lines to the middle of the outer margin.

{221} The caterpillar, which feeds in August and September, on maple, and in the northern counties on alder, is green, inclining to whitish between the rings.
The moth is out in June and early July, sometimes from mid May in warm localities. It is widely distributed over England and Wales, and in the southern counties of England it occurs in hedges wherever the maple grows, but in the midlands and northwards it is chiefly found among alder. In Scotland it is local and rare in Clydesdale, and is known to occur in Perthshire.
Abroad, the range extends to Amurland and Japan.
WAVED CARPET (_Asthena testaceata_).
The typical, greyish-dusted, white form is depicted on Plate 91, Figs. 7 [male] and 9 [female]. Mr. E. R. Bankes states (_Entom._, xl. 33) that in one restricted area in mid-Kent this species varies in the direction of melanism, and he describes two forms as under: ab. _intermedia_ has the usual coloration, but the wings are thickly dusted with dusky brown, chiefly along the front edge of the fore wings, and the cross lines are more distinct than in the type. In ab. _goodwini_ all the wings have the whitish ground colour largely obscured by dusky brown powdering.
The rather spindle-shaped caterpillar is purplish brown, inclining to greenish on the sides and below at each end; on the back of the middle rings are whitish V-marks, and the last three rings incline to purplish red above (adapted from Fenn). It feeds on the young leaves of alder, birch, and sallow, in July and August. The moth is out in June, and hides by day among the bushes, but may be seen occasionally {222} on tree-trunks. Its haunts are in damp woods and plantations, and it occurs in most of the English and Welsh counties, although it is rarely common, except in the south of England. In Ireland it has been noted as scarce in counties Wicklow, Kerry, Galway, and Sligo.
The range abroad extends to Amurland and Japan.
BLOMER'S RIVULET (_Asthena blomeri_).
The earliest British specimens of this species (Plate 91, Figs. 8 [male] and 10 [female]) were taken in Castle Eden Dean, Durham, and among the first to detect these was Captain Blomer, after whom Curtis named the species in 1832. It is still found in that locality, but is also known to occur in Cumberland, Lancs., Yorks., Derby, Staffs., Merionethshire, Worcester, Hereford, Glamorgan, Gloucester, Somerset, Devon, Wilts., Oxford, and Bucks.
The slender caterpillar is yellowish green, generally marked with pinkish-brown on the back, but most or all such markings may be absent. It feeds, on wych elm (_Ulmus montana_) (Plate 90, Fig. 1), in August and September. The moth is out in June and July, earlier or later in some seasons. As a rule, it sits on the trunks of beech trees, but I have seen it on the stems of cherry and fir, though hardly ever on wych-elm. Occasionally, newly emerged specimens have been noted on the leaves of dog's mercury (_Mercurialis perennis_).
The range abroad extends to Amurland and Japan.
LIME-SPECK PUG (_Eupithecia oblongata_).
The characteristic features of this white, or greyish white, species (Plate 93, Figs. 1 and 4) is the bluish grey blotch on the front margin, in the lower end of which is the black discal {223} spot. Occasionally, the blotch is much reduced in size, but it is usually large, and sometimes there are indications of a dusky stripe from it to the inner margin.
When freshly laid, the egg is whitish, but changes to pale orange. The caterpillar (Plate 92, Figs. 2, 2a) is greenish, with more or less connected reddish marks on the back, or green inclining to yellowish, or bluish, without markings. It feeds through the summer on flowers of ragwort, knapweed, scabious, yarrow, golden rod, etc.
The moth, which is often common in gardens, is out from May to August, and specimens of a second brood occur in September and October.
It is widely distributed over the British Islands, but in Scotland it does not, apparently, extend north of Perthshire.
FOXGLOVE PUG (_Eupithecia pulchellata_).
The fore wings are pale ochreous brown with a dusky basal patch limited by a black line; a greyish central band inclining to blackish near the costa, and clouded with ochreous below the middle; the black-and-white edges are wavy; a reddish stripe across the wing before the central band, and a similar, but more irregular, one beyond the band. The hind wings are whitish grey, with several dark-grey bands (Plate 93, Figs. 7 [male], 10 [female]).
In var. _hebudium_, Sheldon, from the Hebrides, the usual reddish stripes are replaced by narrower dark-brown ones; the space left by the reduction in width is white, giving the insect a decidedly grey appearance.
The caterpillar lives in the flowers of the foxglove (_Digitalis purpurea_) and feeds therein upon the stamens and the immature seeds. It enters by boring through the side walls, and then secures the longer lobe of the blossom to the shorter upper one with a few silken threads. Tenanted flowers have {224} a rather faded look and are easily detected. July is the best month, but the caterpillar may be found earlier as well as later.
The moth is out in May and June, and is found in almost every part of the British Isles where the foxglove is common.
TOADFLAX PUG (_Eupithecia linariata_).
Very similar to the last species, but generally smaller, neater and more glossy looking. The central band of the fore wing is blacker, without ochreous clouding below the middle, and the edges are not wavy. The hind wings are darker, and the only distinct band is a whitish one beyond the middle (Plate 93, Figs. 3, 6).
The caterpillar is yellowish green, with a series of dull olive or rust coloured spots or bars along the back, bordered on each side by a dusky olive line; in some examples the markings are absent (Crewe). It feeds in the flowers of yellow toadflax (_Linaria vulgaris_), and may be reared on flowers of the snapdragon (_Antirrhinum_). It is hardly necessary to examine each blossom separately to find the caterpillar, except, perhaps, to make sure when doubtful about the quarry being there. Probably, a handful of the flower sprays gathered in August or September in any locality in the southern half of England where the food plant abounds would furnish moths in the following May or June. The _Linaria_ should be secured on a dry day for choice, but when brought home it need not be put in water; just throw it into an airy breeding cage, and hopefully await emergence of the perfect insects in due course. Sometimes caterpillars attain the moth state the same year.
The range of the species in England extends to Durham, but it seems to be rather uncommon from the Midlands northwards. It is found in Wales, and has been recorded once from Scotland (Inverurie), and once from Ireland (Dublin). {225}
MARBLED PUG (_Eupithecia irriguata_).
The fore wings are whitish and rather shining, the discal spot is black and very distinct, but the dark grey-brown markings, which are only well defined on the front and outer marginal areas, vary in intensity (Plate 93, Fig. 9).
The long, slender and roughened caterpillar is dull yellowish green; three lines along the back, the central one reddish and expanded on the middle rings, the others yellowish; head, reddish. It feeds on oak, in late May and in June. The moth is out in April and May, and is sometimes found on fences or palings in the neighbourhood of oak woods, but may be jarred from the oak boughs, on the undersides of which it usually sits.
The New Forest in Hants is, perhaps, the best British locality for the species, but it has been found in Dorset (Glanville's Wootton), Devon (Exeter district, Tiverton, etc.), Sussex (Abbots Wood, St. Leonard's Forest, etc.), Wilts. (Savernake Forest); also oak woods in Surrey, Berks., Gloucester, Hereford and Glamorgan. On the eastern side it occurs in Suffolk (Bury and Needham), and Norfolk.
DWARF PUG (_Eupithecia pusillata_).
The fore wings of this species (Plate 93, Fig. 12) are pale greyish white, discal spot black, cross lines irregular dark grey inclining to brownish, usually most distinct on the front margin.
The long, slender caterpillar is orange-red or dull ochreous green; three dusky olive lines along the back, the central one often only distinct on the front rings; a yellow line low down along the sides. It feeds, in June and early July, on spruce (_Picea excelsa_). The moth is out in May and June, and rests by day among the branches of the spruce. {226}
The species is very local, but is found in Kent (West Wickham, etc.), Surrey (Mickleham district), Hants (New Forest), Devon (Exeter district, Plymouth), Wilts. (Watlington district), and Suffolk.
OCHREOUS PUG (_Eupithecia indigata_).
Captured specimens of this pale greyish-ochreous-brown species nearly always have a washed-out appearance, and even freshly emerged examples are unattractive. In some specimens, cross lines are more or less traceable on the fore wings; in others four or five tiny dusky dots will be noted on the front edge; as a rule, the only clearly defined character is the black discal spot (Plate 96, Fig. 1).
The long caterpillar is greenish-yellow or yellowish-red; three lines on the back, the central one brownish, but often only distinct on the front rings; the others, and also one low down along the sides, yellowish; head, reddish (adapted from Crewe). It feeds, in June and July, on pine and larch, or may be reared on juniper.
The moth is out in May and June, and sometimes there seems to be another emergence in the latter part of the summer. It frequents pine-woods, where it rests upon the trunks and branches of the trees.
Generally distributed over the whole of England; has been found in South Wales, and occurs in Perthshire, in Scotland. In Ireland, it has been noted from Tyrone, Derry, and Galway.
PINION-SPOTTED PUG (_Eupithecia insigniata_).
The greyish white fore wings have a blackish basal line, and three slender double lines between this and the outer margin; three blotches on the front margin of the wings, the middle one blackish, the others brown with dashes of the same colour below; discal spot, black and streak-like (Plate 96, Fig. 2).
