Mounted
This is a fairly small species with a wingspan of 29–34 mm. It usually has pale grey forewings with darker markings towards the base, including the prominent black mark at the root of the wing which gives the species its common name. However this is a variable species and darker forms exist, including examples of industrial melanism which are prevalent in some towns and cities. The characteristic basal markings are not usually apparent on such individuals. The hindwings are pale or dark grey. The species flies at night in July and August [1] and is attracted to light and sugar, as well as various flowers.
The larva feeds on willows, spinning leaves together in order to feed undisturbed. The species overwinters as an egg.
- ^ The flight season refers to the British Isles. This may vary in other parts of the range.
