The caterpillar is green, with a brownish line along the middle of the back, and a series of pinkish or purplish-red oblique streaks which nearly meet at the central line and so form V-shaped marks; a whitish or yellowish stripe low down along the sides, sometimes edged above with reddish. In some examples the general colour is reddish brown. It feeds in April and May, after hibernation, on bilberry, ling, and heath in a wild state, but may be reared on knot-grass or sallow. The moth is out from June until early August, and may be found resting, often in numbers, on rocks and stone walls in mountain and moorland districts, from Herefordshire, northwards through England, North Wales, and over the whole of Scotland, including the isles, and Ireland. Kane states that in the latter country melanic forms, such as those from Yorks, etc., are nowhere met with. YELLOW-RINGED CARPET (_Entephria flavicinctata_). The general colour of the fore wings of British specimens of this species (var. _obscurata_, Staud.) is slaty grey; the basal, central, and outer marginal cross bands are thickly sprinkled with yellowish-brown, and it is this feature that at once separates this species (Plate 80, Figs. 5, 6) from that last referred to. The bristly caterpillar is green, chocolate, or red brown, but always of a dull shade; on the back is a series of black V-shaped marks, and a central dark, slender line; the front part of each V-mark filled up with pink or lilac, forming a triangle, the apex of which is yellow; a yellowish stripe low down along the side (adapted from Fenn). It feeds in the spring till April, after hibernation, on saxifrage (_Saxifraga aizoides_, _S. hypnoides_, etc), and also on stonecrop (_Sedum_), and is most partial to the flowers of these plants.
