Resident. Larval mines usually occur singly or sparingly in a few deciduous woods and gardens in both vice-counties, although both caterpillars and adults are sometimes common, the last mentioned even at mv light. Nationally double-brooded, flying during July and again from September to April, although the Sussex records of adults chiefly date to August. Larvae feed on poplar, including black poplar and its hybrids, Italian poplar, white poplar and Balm of Gilead poplar. (Pratt, 2011).
