A very rare and local species in Belgium, more observed in the northern part. Sometimes confused with Sciota rhenella.
Native
Wingspan c. 25 mm. It is usually a rather dull-coloured, dark, obscurely marked species, though it is variable, and forms in which the base of the forewing is red- or orange-tinted are very easy to recognise.
The larvae live communally between spun leaves on the food plant. It hibernates as a pupa in a cocoon. The adults come to light.
The adults are on the wing from late May towards August.
The larva feeds on Populus tremula.
The species depends on mature aspen woodland.
