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