The Moths of the British Isles Volume I Part 37

The pale reniform mark on the outer edge of the blackish central area is the prominent feature of this pinkish- or purplish-brown moth. (Plate 141, Fig. 5.) The caterpillar is green, or pinkish-brown, and velvety in appearance; three indistinct lines and some dusky V-shaped marks on the back; a white line along the sides; usual dots white, and the spiracles black. It feeds in August and September on most low plants, birch, sallow, bracken, etc. It is often destructive to ferns in the garden or conservatory; usually selecting the choicer kinds, and as its depredations are carried on only at night, the culprit escapes detection. The moth flies in June and July, and a few specimens sometimes appear in the autumn.

Generally distributed and often common in the South. The range abroad extends to Amurland, j.a.pan, and North America.

THE ANGLE SHADES (_Phlogophora meticulosa_).

The moth shown on Plate 141, Fig. 7, is, when newly emerged from the chrysalis, an exceedingly pretty creature. After death the pinky-brown colour remains, but the olive green of the triangular central band, and border of outer margin, fades and distinctly mars the pleasing effect of the general colour scheme. Sometimes the central band and outer border are red, and in such specimens the ground colour is more rosy. The caterpillar is green or brown, minutely dotted with white; a pale central line and dusky V-shaped marks on each side of it; the outer arm of the V more distinct than the inner; the line along the dark {292} ringed spiracles whitish; head green or brown freckled with darker. It feeds on groundsel, dock, bracken, and almost anything in the way of an herbaceous plant; often attacks geraniums in the greenhouse as well as outdoors. Has been found in almost every month of the year, but perhaps most common in July, August, and September. The moth also occurs at all seasons of the year, but seems to be most frequent in May and June, and sometimes in September and October. It is found throughout the British Isles. Both this species and the last mentioned, when resting on herbage, paling, or tree stem, chiefly the former, sit with the wings folded in to the body, but each fore wing is broadly wrinkled or folded throughout its length. In this position the moth is very like a crumpled decaying leaf, and for such may be readily mistaken.

THE OLD LADY (_Mania_ (_Mormo_) _maura_).

From its habit of creeping behind curtains, shutters, etc., and otherwise disposing itself in dwelling-houses during the day, as well as in summer houses and other buildings, this moth (Plate 142, Figs. 1[male], 3[female]) must often come under observation. The caterpillar is ochreous brown with a darker diamond pattern on the back; the central line is ochreous, but much broken, and on each side of it there is a series of pale oblique streaks; the spiracles are reddish ochreous, edged with black, and the line along them is ochreous; head pale brown, glossy. The general colour varies to greyish or purplish brown. It feeds on various low herbage in the autumn, and on the young shoots and leaves of sallow, hawthorn, birch, etc., in the spring after hibernation. The moth flies in July and August, and is generally common in the south of England. Sometimes it abounds even in the London suburbs, and in 1904 it was seen pretty frequently during August flying, in the evening, low down along the roads and in gardens all over the southern district. The species is also {293} found more or less frequently throughout England northwards, and well into Scotland, as least as far as Clydesdale. Renton records it as common at sugar in Roxburghshire, and White gives the Forth and Tay districts. Widely distributed in Ireland, common in some parts.

THE GOTHIC (_Naenia typica_).

This moth (Plate 142, Fig. 2) is common in gardens, as well as along the weedy wayside and hedgerow in all parts of England and Wales, Scotland to Sutherland, and in Ireland. The caterpillar (Plate 139, Fig. 2) varies in colour from brownish-grey to pale ochreous brown, or greenish grey, freckled with darker; three pale lines on the first ring, and partly on the second; some pale oblique streaks on the sides, and blackish marks on rings ten and eleven, the latter more or less united behind; head of the body colour darker marked. It feeds on all kinds of herbage, also on the leaves of sallow, sloe, apple, etc. When young in large companies on the underside of leaves. August to May. The moth flies in June and July.

THE CRESCENT (_Helotropha leucostigma_).

Of this purplish-brown species the typical form (Fig. 1), and the pale banded form, var. _fibrosa_, Hubn., are shown on Plate 143. The caterpillar, according to Buckler, is slaty brown, inclining to olive drab above; three paler lines on the back; the spiracles are black and the usual dots black-brown; head warm brown, very glossy; plate on first ring glossy black, that on the last ring blackish brown. It feeds in the stems of _Cladium mariscus_, sedge (_Carex paludosa_), and yellow flag (_Iris pseudacorus_). May to July. The moth is out in late June, July, and August.

It inhabits fens and marshy ground, and seems to be found in such localities throughout the British Isles, including the {294} Hebrides and Shetlands. Abroad the range extends to Amurland, China, j.a.pan, also North America.

THE EAR MOTH (_Hydroecia_ (_Gortyna_) _nict.i.tans_).

On Plate 143 are shown a more or less typical specimen of this species (Fig. 3); the reddish spotted var. _erythrostigma_, Haw. (Fig. 4); and two examples of the marsh or saltern form, _paludis_, Tutt (Figs. 5, 6), for which specific rank has been claimed. Specimens found in marshes, especially those by the sea, are usually somewhat larger than normal, but I cannot see that they otherwise differ from forms of _nict.i.tans_. The caterpillar is greenish pink with pinkish grey stripes on the back and sides; spiracles black, and usual dots dark brownish; head pinkish ochreous, plate on ring one of the body yellowish brown. It feeds from May to August on gra.s.ses, chiefly the lower part of the stems. The moth flies in August and September, and is sometimes seen in the daytime on the flowers of thistle and ragwort, etc., but far more frequently at night, when it also visits sugar more or less freely. Usually common in marshy places throughout our islands. The range abroad extends to Amurland, Corea, j.a.pan, and North America.

THE ROSY RUSTIC (_Hydroecia_ (_Gortyna_) _micacea_).

This moth (Plate 143, Figs. 8, 9) is also widely spread over the British Isles, occurring most freely on the coast, but not uncommonly inland. It appears in the autumn, and is frequently seen at light, and although not very partial to sugar it occasionally visits that attraction as well as ragwort blossom, etc. The caterpillar is dull smoky pink, with a faintly darker central stripe; the usual dots dark brown, and the spiracles black; head, and plates on first and last rings of the body ochreous brown. May to August on dock, plantain, feeding in the stems and down into the roots.

Sometimes it attacks the potato, eating down the stalk into the tuber. The range abroad extends to Amurland.

{295} THE b.u.t.tERBUR (_Hydroecia_ (_Gortyna_) _petasitis_).

This is a larger species than the last, and more dingy in coloration. Its chief haunts, among the b.u.t.terbur (_Petasites_), are in the northern counties from Cheshire to Durham. It was first met with by Stainton in 1846 at Falkirk in Scotland, and Doubleday named and described it in 1847. An account of its caterpillar feeding in the roots of the b.u.t.terbur was published by N. Cooke in 1850, and by 1855 the northern collectors had reared and distributed large numbers of the moths among their confreres in other parts of the country. The species is still common in the north of England, but continues scarce and very local in Scotland. Odd specimens have been reported from the eastern counties and once from Somerset. The caterpillar is greyish white with black dots; head, and plate on first ring of the body brown. July and August. The moth occurs among its food plant in August and September. (Plate 143, Fig. 7.)

THE FROSTED ORANGE (_Ochria ochracea_).

Except that it sometimes visits a strong light, and may then be captured, this moth (Plate 144, Figs. 1[male], 2[female]) is most easily obtained in its early stages. The caterpillar is pale ochreous white with conspicuous black dots; head ochreous brown, the plate on first ring of the body is blackish with white lines upon it. It feeds in the stems of thistles, burdock, hemp-agrimony, etc. April to July, or later. The brownish chrysalis may be found in stems of the plants, generally low down near the ground. The moth, also known as _flavago_, Schiff., occurs from August to October in most places, especially marshy ground, where {296} thistles flourish, throughout England and Wales. It is found in Scotland up to Perthshire and Aberdeen. Only recorded from Wicklow, Galway, Sligo, and Clare, in Ireland.

REED WAINSCOT (_Nonagria algae_ (_cannae_)).

This moth (Plate 144, Fig. 4) varies in size and also in the colour of the fore wings, which range from a pale ochreous, through reddish shades, to sooty brown. The cross lines are indicated by black dots. The black dotted greenish caterpillar has a brown head and a whitish green plate on first ring of the body. It feeds from May to July in the stems of reed-mace (_Typha latifolia_), often called the bulrush or catstail; also in the true bulrush (_Scirpus lacustris_). Fig. 5, Plate 148, shows the chrysalis in its characteristic position when in the stem, that is with the head upwards. The moth flies, in August and September, at dusk, over and among the reeds; the males especially freely responding to the attraction of light. Its chief localities are in the fens of Norfolk and Suffolk, but it has also occurred in Mid-Suss.e.x.

WEBB'S WAINSCOT (_Nonagria sparganii_).

This moth also varies in the colour of the fore wings, from almost whitish through various shades of ochreous and red. The main veins are shaded with grey, and the median one has black dots upon it, chiefly at the end of the cell; the outer margin with a row of large or small black dots. (Plate 144, Fig. 3.) The caterpillar is yellowish green with darker lines; head and plate on first ring of the body pale brown. It feeds in July and August in stems of bur-reed (_Sparganium_), reed-mace, and yellow flag. Fig. 6, Plate 148, shows the chrysalis in its natural position in the stem. The hole in the stem from which the moth escapes is also clearly in evidence above the chrysalis. {297} The moth flies among reeds, etc., in August and September.

Its chief localities in England are in East and South-east Kent, in which county the first British specimens were obtained by Mr. Sydney Webb in 1879. In 1899 a specimen reared from a caterpillar found in a stem of _Typha_, was recorded from Suffolk (Woodbridge district); and in 1901 the species was recorded from South Devon. It is also not uncommon "between Old Head of Kinsale and Glandore," Co. Cork, Ireland.

THE BULRUSH WAINSCOT (_Nonagria typhae_).

The fore wings of this species (Plate 144, Fig. 5), usually of a pale whity-brown colour, in some specimens are reddish tinged; or they may be almost uniformly reddish brown or blackish (var. _fraterna_, Treit.). The row of black spots on the outer area are wedge-shaped and are placed just before the margin. The caterpillar is pale ochreous more or less tinged with pink; a paler line along the spiracles; head and plate on first ring of the body red-brown. July to August, in stems of _Typha_. The moth flies in August and September, and although it may be netted when on the wing at dusk, or at light, it is obtained in better condition by rearing it from the chrysalis, which may be found in the stems (Plate 148, Fig. 3), those of the previous year for choice, of reed mace. Generally distributed in England up to Yorkshire; it has been recorded also from Northumberland and the Scottish border. It is common in southern Ireland, and found northwards up to Sligo, Tyrone, and Armagh.

THE TWIN-SPOTTED (_Nonagria geminipuncta_).

This species, shown on Plate 144, Figs. 6, 7, varies in colour from pale brown, more or less suffused with grey, through darker, or reddish brown to blackish (var. _nigricans_, Staud.). {298} In the brown typical form the reniform mark is represented by two dark-edged white dots, the upper one often tiny or absent (var. _unipuncta_, Tutt), or both may be absent (var.

_obsoleta_, Tutt). The caterpillar in pale ochreous, pink-tinged, a pale line along the spiracles; head dark brown. May and June, in stems of reeds (_Phragmites_). The chrysalis lies in the reed stem with the head towards the oval hole above it from which the moth escapes. In August the moth may be found in its haunts in the south and east of England. These are marshes, often near the sea, in Cambridgeshire, Suffolk, Ess.e.x, the Thames valley, Suss.e.x, Hants, and the Isle of Wight, Wiltshire and Somerset.

THE BROWN-VEINED WAINSCOT (_Nonagria dissoluta_).

The popular name applies more especially to the ordinary form of this species known as _arundineta_, Schmidt. (Plate 144, Fig. 8.) The dark brown or black typical form (_dissoluta_, Treit. = _hessii_, Boisd.) is local and uncommon; in fact until 1900 it had not been noted in England for a number of years, and specimens were only known from Yaxley. In the year just mentioned however, several examples of it were recorded from Suffolk, taken in the Needham Market district; and in 1905 specimens were reported from the East Kent marshes. Var. _arundineta_, the _neurica_ of some authors, occurs in the fens of Norfolk, Suffolk, Cambridge, and Lincolnshire; also in marshes in Ess.e.x and Kent; and is said to have been taken in Middles.e.x and Lancashire. The caterpillar is dirty white, light reddish on the back; raised dots black inclining to brown on front three rings; spiracles white edged with black; head dark brown; plate on first and last rings of the body brownish grey. It feeds in June in the stems of reed and turns to a chrysalis in the lower part of the stem, head downwards in the direction of the exit hole below it. (Plate 148, Fig. 1.) The moth flies in July and August.
