An uncommon and local species throughout Belgium, more observed in the northern part.
The larva lives at first on the catkins of the host plant, later between spun leaves. Hibernates as a pupa in an underground cocoon. The adults come to light and occasionally on sugar.
Depending on mild conditions, the first adults can be seen from mid February onwards, but usually they fly from March till May in one generation a year.
The larva lives mainly on Populus tremula, also reported on other deciduous trees.
