rather common species throughout Belgium.
larva lives on various herbaceous plant species. It does not feed
before hibernating. After hibernation, it first mines a leaf, then
lives between leaves spun together. It pupates in the larval habitation,
or spun up nearby on the plant.
adults have been observed from mid May till till August.
