The moth is on the wing in June and July; in forward seasons as early as the end of May. On a sunny afternoon it may be seen careering around trees, generally pretty high up. When resting the moths sit about on the trees or on the herbage under them. In some years it occurs in large numbers, but it is not usually very abundant, and sometimes even in its best localities only a few specimens will be seen during the season. It frequents woods, especially the larger ones, throughout the southern half of England up to Norfolk on the east, and Hereford on the west. In the northern counties it is rare, and is not common in Scotland or Ireland. Abroad, its range is through Central and Northern Europe, except the extreme north, to Dalmatia, Altai, and Amurland. THE MUSLIN (_Nudaria mundana_). This delicate little moth has the semi-transparent fore wings pale greyish, faintly tinged with brown; crossed by irregular brownish lines; the hind wings are paler, shaded with a darker tint on the outer margins. Occasionally all the wings have a smoky tinge. The moth is shown on Plate 95, Figs. 3, 6, and the caterpillar and chrysalis on Plate 94, Fig. 2. [Illustration] Pl. 94. 1.

Head black, shining; face yellowish. It may be found in April and May, after hibernation, on rocks, stone walls, especially those formed of loose cobbles or shale, trees, bushes, and even gate posts. I have beaten them from an old hawthorn hedge bordering a damp meadow in Middlesex, and collected them in numbers from the hollows of field boundary walls in North Devon. They feed on the tiny lichen that grows in such places as those indicated. The green, or yellowish-green chrysalis, is enclosed in a rather loose muslin-like silken cocoon, and is not difficult to obtain, especially from walls. It appears to be pretty generally distributed throughout England and Wales, except perhaps the midland and eastern counties; it occurs in the east and west of Scotland. In Ireland it is common, and often abundant, locally. Distribution: Northern and Central Europe. THE ROUND-WINGED MUSLIN (_Comacla senex_).
