rather rare species in Belgium, but probably overlooked.
larva makes small mines with one strong central crease on the underside
and rarely on Prunus.
Pupates in a dark brown pupa in a very flimsy cocoon.
adults fly in two generations a year; May and
August. As in Britain, there is recently a third larva generation found on evergreen Oak during the period December - March.
