This appears to be a quite worn specimen. The ALA and the AFD now appear to favour the name Stericta phareopteralis rather than O. phaeopteralis. Clearly S. orchidivora and S, phaeopteralis are similar looking species. In this specimen I see no evidence of the greenish forewing colouration said to be typical of S. orchidivora. Also I do not see the pattern mid way along the costa which seemes to be characteristic of S orchidivore. However the dot pattern I do see seems to be more typical of S. phaeopteralis. On this admittedly sketchy basis I therefore suggest S. phaeopteralis.
