The caterpillars make dirty white blotch mines that are preceded by a short corridor that starts at the midrib. Most of the frass is removed from the mine. The caterpillar makes several mines.
The adults overwinter.
The adult moths fly from late June onwards, hibernate, and reappear up to May the following spring.
