A very rare species in Belgium, but probably overlooked in many places.
See also bladmineerders.be
The young larva makes a blotch mine in the leaf tip of different species of the food plant. The larva is capable to rest at a new leaf when the old leaf is mined out.
The adults fly in two generations a year, during May and August.
The larva lives on Hypericum.
