Very rare immigrant from southern and central Europe to the Channel Islands, where first recorded in 2005. In Hampshire recorded for the first time at Stubbington on 24 April 2011, the first and as of 2025, so far the only record for the British mainland. Not recorded from the Isle of Wight to date. Wingspan 17-19 mm. Larva feeds on Oak, no evidence of breeding in the UK. Originally thought to represent Elegia fallax, but this species has been split and it was found that both the Hampshire and Channel Islands specimens refer to the present species.
