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.
Native
The larvae can sometimes be found between the foliage on the epicormic growth under the tree canopy. Hibernates as a pupa in a thin and sturdy cocoon in a folded leaf. Both sexes come to light, but the main flight appears to be for a couple of hours from dusk.
The adults fly from mid-May towards early Sepember, although most specimens have been seen during July.
Deciduous forest with big stands of mature Tilia trees, old alleys etc.
