The caterpillar, which feeds in August and September, on maple, and in the northern counties on alder, is green, inclining to whitish between the rings.
The moth is out in June and early July, sometimes from mid May in warm localities. It is widely distributed over England and Wales, and in the southern counties of England it occurs in hedges wherever the maple grows, but in the midlands and northwards it is chiefly found among alder. In Scotland it is local and rare in Clydesdale, and is known to occur in Perthshire.
Abroad, the range extends to Amurland and Japan.
Waved Carpet (Asthena testaceata).
The typical, greyish-dusted, white form is depicted on Plate [91], Figs. 7 ♂ and 9 ♀. Mr. E. R. Bankes states (Entom., xl. 33) that in one restricted area in mid-Kent this species varies in the direction of melanism, and he describes two forms as under: ab. intermedia has the usual coloration, but the wings are thickly dusted with dusky brown, chiefly along the front edge of the fore wings, and the cross lines are more distinct than in the type. In ab. goodwini all the wings have the whitish ground colour largely obscured by dusky brown powdering.
