A very rare and recently discovered species (2018) in the south of Belgium, hitherto only observed in NA.
A large Acleris with a wingspan of 26 to 28 mm. Forewing broad and slightly concave with small minute groups of erected scales scattered over the wingsurface, most obvious in the median fascia. Ground colour of forewing ash-grey, spots and markings darker, usually three hazy spots at the level of the costal blotch, furthermore several dark transverse lines at the rear of the forewing. Cilia whitish, hindwing brown. Little variation in colour and pattern within this species.
Larvae can be found from June to July in spun leaves of the hostplant.
From August onwards and after hibernation again till April.
Most literature sources mention Populus tremula, other older sources also claim Betula.
