A fairly common species throughout Belgium. Easily confused with Acleris notana and therefore it is best to check the genitalia.
It is the most common of both species.
Wingspan 14–18 mm. This species is very similar to Acleris notana and both are equally variable.
They can only be reliably separated by genitalia dissection.
The larva lives between two leaves spun together and pupates there. The adults hibernate.
The adults come to light.
The adults fly in June/July and again from August/September till November, the second generation overwintering to reappear in spring till May.
It inhabits woodland, parks and gardens.
