A fairly common species in Belgium.

The larva lives inside a blotch mine on Betula and Ulmus. A light web is spun beneath the mine and the larva moves between web and leaf. Frass is ejected from the mine and collected on the web. It hibernates in a cocoon within the mine, later it pupates in a boat-shaped cocoon amongst debris on the ground.

The adults fly in one generation a year during June and July.
