The distribution abroad includes Amurland and Japan. LATTICED HEATH (_Chiasmia_ (_Strenia_) _clathrata_). In its ground colour this species (Plate 143, Figs. 7, 8 [male], 9 [female]) varies from ochreous of some shade to white. The dark-brown or blackish cross lines and veins give a latticed appearance to the wings, hence both the Latin and popular names for this insect. There is much variation in the width of the cross markings; sometimes two or more unite and so form bands; more rarely, perhaps, the outer lines are absent, and the others broken up into dashes; or the blackish cross lines may be slender and the veins remain of the ochreous ground colour (ab. _radiata_, Haworth). A less frequent aberration has the wings dark brown or blackish all over, except a row of whitish or ochreous spots on the outer margins (ab. _nocturnata_, Fuchs = _nigricans_, Oberthur). The caterpillar, which feeds on clovers and trefoils, is green, with white lines along the back and sides; the slightly notched head is rather glossy, and the mouth is brownish: June to September, in two broods. The first generation of the moth is out in April and May, and {329} the second in July and August. It may be found in clover fields and on chalk slopes, etc., where the food plants flourish; although it is an active day flyer, it is not difficult to capture with the net. It is most plentiful in southern and eastern England, but its range extends throughout the United Kingdom to Clydesdale, and the species is widely distributed in Ireland. The distribution abroad extends to East Siberia, Amurland, and Japan. GREY SCALLOPED BAR (_Scodiona fagaria_). In its typical form this species (also known as _belgiaria_, Hubner) is grey, more or less tinged with ochreous, speckled with brownish grey, and crossed by black-marked brownish-grey lines. The bulk of British specimens, especially those from southern localities, are whitish grey, thinly sprinkled with darker grey scales in the male, and sometimes heavily powdered in the female; a pair are figured on Plate 144, 1 [male], 2 [female]. The whiter form of the male, occurring in Britain chiefly in the New Forest, Hampshire, has been named _albidaria_, Staudinger. The roughened caterpillar is figured on Plate 142 (photo by H. Main). In general colour it is dingy brown, with a whitish stripe along the back and some greyish marking on the sides. It feeds on ling and heath; growing slowly in the late summer, but more quickly in the spring, after hibernation, when it may be obtained at night from the tips of the heather twigs, either by searching or by means of the sweeping net. The moth is out in June and July in the south, and later in the north. It is found on moist heaths, moors, and mosses; when resting on the dark-coloured earth it so closely resembles a stone that it is probably frequently passed unnoticed.
