A fairly common species in Belgium.
Native
The larva makes a leafmine usually starting close to the midrib or near the leaf edge on the upper- or underside of small-leaved willows. Pupates in a dark reddish brown cocoon covered with fluffy silk.
The adults fly in two generations a year during May and June and again in September.
The larva lives on willows like Salix alba, S. babylonica, S. fragilis, S. pentandra and S. viminalis.
