Pupation takes place inside a tough silken cocoon.
Bionomics
Most likely, the egg is laid in a leaf bud. The mine is a large blotch mine that is located close to the leaf margin sometimes partially curling the leaf. The black frass normally lies, as with all Eriocraniidae, in so-called spaghetti strings but this is less distinct with this species or even completely absent. In that case, the frass is present as scattered grains.
The pupation takes place outside the mine.
The adult moths often fly in the sunshine around the host plants.
Flight periods
The moths are on the wing in April.
Observed on
