Specimens in nature


The case look like a willow catkin, because of the use of so many different host plants, the case can look very different.
The mouth angle is 70°.


The young larva feeds on the developing seeds and hibernates in its first case which is made of the tip of a petal. After the winter the larva makes a composite case resembling a willow catkin.
The larvae live mostly at the tip of a leaf or the fleck mines are made at the margin of the leaves, that thereby look peculiarly damaged.
Larvae are full grown in mid May – early June.
Before pupating the larvae may wander around a lot, so they can be found at many different plants being not there feeding plant.
The adults come to light.
