A very rare species in Belgium.
Native
The young larva makes a circular blotch mine in the leaves of the food plant. Later on it constructs a flat oval case cut from the mine which is subsequently enlarged to a fiddle-shaped case with silk and plant hairs. Caterpillars living on Fragaria cut off a segment from the tip of the leaf and attach it to the underside of the same leaf, feeding on it as they wither. Caterpillars living on Geum feed on the underside of the older leaves from the ground.
Pupation takes place in the case.
The moths are active during the day, they prefer bright sunshine.
The adults fly from early May till mid-July.
The young larva lives on: Fragaria vesca or Geum rivale.
