Food Plant: Populus nigra (Black Poplar), P.alba (White Poplar), P x canadensis (Italian Poplar), P x canescens (Grey Poplar)

Mine: September-May

Notes: The larvae first feed in a short linear mine alongside the midrib or a vein (Hering, 1951, 1957) and then start window feeding beneath a frass covered silk web on the leaf underside (as shown on P x canescens (Grey Poplar)) . In the spring they feed on the buds in a frass covered silken tube.
