A very rare but widespread species in Belgium.
They are active during sunshine and come to light and are also attracted to the pheromone of Cydia fagiglandana.
The adults fly onwards from late April towards June.
The larva lives in a spun leaf or between two leaves spun together on Lathyrus sylvestris. It overwinters in its cocoon from the end of August and pupates in a cocoon spun amongst leaf-litter in April..
