A very local and very rare species in Belgium, only recorded from a few localities in the extreme south in LX were a stable population exists.
Hibernates as pupa in a thin and sturdy cocoon in a folded leaf. The adults come to light.
The adults fly from mid May towards late July. Most Belgian records are from July.
The larva lives on Tilia cordata.
