A very rare species in Belgium, not seen for a long time. Some individuals resemble Acleris ferrugana (but usually more faintly marked and never showing clear black spots on top of forewings).
The museum specimens depicted here show great resemblance to Acleris ferrugana. The typical form of A. quercinana is not depicted here and the genitalia show similarity with Acleris ferrugana, leaving the question whether A. quercinana belongs to the Belgian fauna or not.
The larva lives between spun leaves.
The adults are on the wing from mid-June till late October.
The monophagous larva feeds on Quercus.
