Formerly regarded as a very rare immigrant from mainland Europe, this species has been recorded in increasing numbers since the first authenticated British record was made at Minsmere, Suffolk, in 2009 with two further reports from the same county in Bawdsey, June 2010. It has established a breeding population in East Anglia and appears to be spreading. Discovered in north Hampshire in 2020 for the first time. Wingspan 12-16 mm. Larva feeds within fruit of Norway Maple, Field Maple and Sycamore.
