Synonyms and other taxonomic changes

Euchlaena johnsonaria (Fitch)

Orig. Comb: Priocycla johnsonaria Fitch 1869

Euchlaena mollisaria was synonymized by McGuffin (1981), but not accepted by all.

Syn:Euchlaena bilinearia (Packard, 1870)

Identification

Ground colour varies from light to dark rust-brown, AM and PM line thin and well defined, median line diffuse. Most specimens have diffuse black spots in the forewing subterminal space (but may be without any black at all). Similar to E. madusaria, which has a smooth rather than serrate forewing edge. E. johnsonaria has evenly deep serrations on the hindwing edge, obtusaria has the third notch conspicuously deeper; hindwing discal spot absent or faint in johnsonaria, well-defined in obtusaria.

Life Cycle

McGuffin (1981) describes the larva in detail. The adults are attracted to lights
