It livesupon honey-suckle, and feeds on the leaves at night, duringMay and June, or sometimes later. _ The moth appears in March and April, and, in the davtime,is often met with at rest on posts, fences, and the trunks oftrees ; also upon stone walls, but seemingly less frequently,probably owing to the moth being then less easy to detect.
