A not very common species in Belgium, recorded from almost all provinces but probably overlooked in many places.
The larva first lives in a small, hard to observe gallery at the underside of the leaf which is later enlarged into a small, transparant blotch mine.
A whitish silken cocoon.
At first a small gallery, then a whithish blotch and later on a leaf roll, made by cutting part of a leaf and rolling that part up and spinning it to the leaf.
Pupation takes place in the leaf roll where the larva first spins a whitish silken cocoon.
The species hibernates in the adult stage. The adults come to light.
The moths fly from August till early June in one generation per year.
The species prefers rather wet habitats where the foodplants grow, like meadows, river banks, etc.
