Taxonomy
Superfamily: Noctuoidea Family: NotodontidaeSubfamily: HeterocampinaeP3 Number: 930105 MONA Number: 8012.00 MONA Synonym: Oligocentria semirufescens
Identification
Field Guide Descriptions: Covell (1984); Beadle and Leckie (2012)Online Resources: MPG, BugGuide, iNaturalist, Google, BAMONA, GBIF, BOLD                                                                                 
Adult Markings: The forewings are dull reddish with a variable amount of luteous shading (Forbes, 1948). The basal dash is nearly obsolete and a dark patch is located over and/or beyond the reniform dot; in our specimens this patch is greenish rather than blackish and there are additional greenish streaks in the subterminal area. Our specimens often have another dark tornal patch and a pale, subapical streak. A pale postmedian is usually traceable near the inner margin. The thorax is gray and contrasting. Oedemasia concinna is similar but smaller and lacks the dark patch over the discal dot.
Wingspan: 40 mm (Forbes, 1948)
Adult Structural Features: The eighth sternite of the males is simply emarginate rather than notched, as in Oedemasia concinna (Forbes,1948). The forewing is more pointed than in concinna, which is usually truncated.
Adult ID Requirements: Identifiable from good quality photos of unworn specimens.
Larvae ID Requirements: Identifiable from good quality photos, especially where associated with known host plants.
