SeasonalityIn Alberta adults fly from in June and July, peaking in late June. IdentificationGround 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. 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.
