A not so common species throughout Belgium.
Native
The caterpillar is monochromatic yellowish-white.
The larva lives between two leaves, which are spun tightly together or under a turned leaf edge. It hibernates full-fed in a cocoon spun at ground level and pupates in that cocoon.
The moths are active towards dusk and later come to light.
The adults have been observed from late April till mid-July, occasionally later.
The larva lives on rough-leaved Salix species like Salix caprea, Salix cinerea and Salix aurita. Most found on Salix caprea.
It inhabits damp and deciduous wooded areas.
