First recorded in Britain from West Sussex in 1983, with increasing records in recent years, covering nearly every southern county by 2021!
Similar to the Flame Shoulder (O. plecta), but larger, has a clean straight costa and elongated forewings with smaller stigmata and whiter hindwings. Usually a much later flight period, but late examples of plecta do also occur.
