Distribution


Imago

Wingspan 16–20 mm. The posterior edge of the dark area in A. betuletana is straighter so that it does not reach so far back along the costa as in A. capreana or A. turbidana.
The central pale deviation into the dark area is also less pronounced in A. betuletana and it can have a light ochreous clouding in the pale area.
