Present in most areas of Belgium.
The adults have been observed from late June till the end of August. They are active in late afternoon and later come to light.
The larva lives in a shoot or leaf-stalk of Populus spp. An erect conical tube of frass at the entrance hole indicates the feeding-place. Pupation in a cocoon in a crevice of bark or amongst leaf-litter.
