A rare species throughout Belgium.
The adults have been observed from early July till the end of September. They are active at dusk and later occasionally come to light.
The larva lives in a folded leaf or between spun leaves, usually at the end of a shoot, of Betula spp., favouring small trees. It pupates in a flimsy cocoon in the earth or amongst leaf-litter.
