The Suspected (Dyschorista suspecta).
Of this species (Plate [4], Figs. 2 and 3) there are two groups of forms—plain and variegated. To the first belongs the type with reddish-brown fore wings; a dark modification of this form is ab. nigrescens, Tutt, which has the fore wings blackish red; a brighter red form is ab. rufa, Tutt. Of the variegated sections three forms have been named, but the most important of these is var. congener, Hübn., with the inner and the outer marginal areas of the reddish fore wings ochreous; two other modifications have the ground colour redder or dark purplish inclining to blackish.
The caterpillar, which feeds on birch and sallow in April and May, is purplish brown above, and obscure greenish beneath; there are three lines along the back, the central one white and distinct, the others less defined but noticeable on the black plate on ring nearest the head; on each side of the central line are blackish marks; head, ochreous brown, streaked with black.
The moth flies in July and August, and is partial to sugar and to the flowers of heather and ragwort. Its chief British quarters appear to be in Yorkshire, in which county it was first noted in 1841; thence it extends into Lancashire, Cumberland, and Durham, but is local and scarce in the latter county. Southwards it is found in the counties of Cheshire (locally not uncommon on moors and mosses), Derby, Nottingham, Stafford, Shropshire, Warwick, Gloucester (rarely); more locally in Norfolk, Suffolk, Essex, and Kent (once at West Wickham). In 1896 it occurred in numbers in the New Forest, Hants, and I believe that a solitary specimen was secured in Hayling Island in 1901. In Scotland it occurs up to Inverness and Aberdeen; and Kane states that in Ireland it is doubtfully recorded from Londonderry, but that he has seen lovely forms of the species from Killarney. It also occurs in Co. Wicklow. The range abroad extends to Siberia, Amurland, and Mongolia.
