A very rare species in Belgium, not often observed.
Native
Wingspan 16–22 mm. A very variable species. Specimens do occur without the obvious contrast between light and dark, or with obscure markings and these can be confused with related species.
Distinguished from Epinotia sordidana and related species by its whitish grey hindwing
The young larva is light grey with darker to black warts, head and prothoracic plate black, anal valve greyish to black. As the larva gets older, the head turns brownish, warts become lighter and the anal plate has the same color as the light greyish to whitish body.
The larvae live among spun leaves. The adult is not easily observed, though it does come to light.
The adults are on the wing from mid-July towards late October.
The main foodplant are narrow-leaved species of Salix, also known from Myrica gale.
It frequents wet moorlands, marshes and fens.
