73.330 Ochropleura leucogaster (Radford's Flame Shoulder)
fw: 13-16mm; rare migrant, first recorded 1983 with 29 records prior to 2015, but many more in 2015 to 2018; all S.coast of England, late Sep to Nov.
ID: Very similar to O.plecta (Flame Shoulder), both having a brown forewing ground colour with a sharply contrasting pale straw costa and a black streak from near wing-base through the oval and kidney marks. Distinguished on the following features: averages larger and more elongate (vs 12-15mm); forewing ground colour dull brown (vs reddish-brown); oval and kidney marks small (vs larger); hindwing clean white (vs glossy yellow-white); strong contrast between purplish thorax and whitish patagia; white hairs around anterior part of abdominal dorsum; black streak extends distal to kidney mark (usually stops at the kidney mark in O.plecta). All British records have occurred late September to November after the normal flight period for O.plecta. See Ochropleura for more detail on separating these two species.
