The moth is out in July, and sometimes an odd specimen or two will appear in the autumn; one was captured at Gravesend on October 22, 1904.

The species is represented in Amurland and Japan by the smaller and whiter var. persica, Ménetries.

Scorched Wing (Eurymene dolabraria).

The crumpled or shrivelled appearance of the wings, coupled with the brown coloration of the streaks and other markings on the wings, no doubt suggested the English name of this species (Plate [117], Fig. 3).

The twig-like caterpillar is brownish, tinged with greenish or reddish, and variegated with darker, especially along the back of the first three rings, the hump on ring 8, and a cross stripe on the last ring. It feeds on oak, birch, and sallow, from July to September.
