scientific name    Euchlaena johnsonaria    

habitat
Deciduous wooded areas in the southern half of the province.

seasonality
In Alberta adults fly from in June and July, peaking in late June.

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

conservation
Not of concern.

range
Southern coastal BC east to Nova Scotia, south to NJ, MO and OR (McGuffin 1981).
