Host plants:
The larvae feed on birch (Betula).

Habitat:
Achlya flavicornis inhabits birch-rich woodlands of all kind, especially in wetlands.

Life cycle:
The moths occur between late February and May with strong peak in March. The larvae live between mid-April and June in leaf shelters. They are also observed on small bushes. The quite developed adults hibernate within the pupa.

Endangerment factors:
Achlya flavicornis has already declined as economical worthless birches are less and less tolerated by forestry.

Remarks:
Achlya flavicornis is observed in Europe and temperate Asia to Japan.
