known from the southern half of Belgium.
young larva makes a circular blotch mine in the leaves of Fragaria
vesca or Geum rivale. 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
adults fly from early May till mid June. The moths are active during
the day; they prefer bright sunshine.
