A common moth in England but more local further north. Rests with wings tightly rolled, resembling a small cross. Usually a greyish-white to brown in colour. Each pair of spurs on the hind legs has one spur longer than the other.
Caterpillars feed in two overlapping generations from late May to September.
The adult moth is often seen on fence posts, walls and even indoors where they are attracted to light. Can also be found at Ivy blossom, ripe blackberries and, in spring, at sallow blossom.
