Life cycle

Larvae present July-August, October-June.  Larva initially mines a leaf then, for the winter, it transfers to the bark just below a bud. In the spring it mines a shoot which then droops.  The summer brood sometimes lives within the galls of mite Aceria fraxinivora, the galls made on inflorescences.

Larval foodplants

Ash or Wild Privet.
