The flame shoulder (Ochropleura plecta) is a moth of the family Noctuidae. It is distributed throughout the Palearctic from Ireland in the west to Siberia then Korea and Japan in the east.
The forewings of this species are reddish brown with a black streak interrupted by white stigmata and a creamy-yellow streak along the costa which gives the species its common name. The hindwings are pure white.
Technical description and variation
The wingspan is 28–34 mm. Forewing red-brown suffused with purple; costal streak broadly cream-colour to outer line, sometimes red speckled; cell and a basal streak below median vein blackish or deep red;orbicular and reniform stigmata with bright pale rings and grey centres, the latter followed by a small black blotch; lines rarely visible; hindwing whitish; patagia red-brown; dorsum greyish fuscous, sometimes with basal half cream-coloured, sometimes wholly cream-coloured.ab. unimacula Stgr. [now ssp.] from Spain has the orbicular stigma obsolete; — in ab. anderssoni Lampa from Scandinavia the forewing is blackish purple; in ab. glaucimacula Graes. from Amurland the stigmata are smaller, as in leucogaster Frr.[now full species] and pearl grey in colour; the outer line of forewing well-marked and indicated on hindwing also by vein-dots; patagia black-brown; — ab. ignota uncertainly ranked by Swinh., described in the first instance from Sri Lanka, has the cell red like the rest of wing; European examples of this form are generally entirety pale red, with the costal streak red-speckled and usually females..[1]
