A very rare and local species in Belgium, only found in LI.
Lobe case. Each lobe consists of a mined leaflet, therefore it has a rather whitish look.
The mouth angle is between 20°–40°.
See also bladmineerders.be.
The small leaves of the food plant are completely mined and become rather white. The caterpillars are fully grown in June. <br Pupation takes place low on the stem of the food plant.
The adults are on the wing from late June till the whole of July.
