Identification
The following loosely applies to the 2 mentioned species. There is just too much variability for these descriptions to be valid much of the time.
Adult: two dark bands on each forewing almost touch each other near the midline, and the inner (or more basal) band touches the inner margin [whereas in Caenurgina erechtea, the bands do not touch each other near the midline, and the inner (or more basal) band does not touch the inner margin]. The color can vary but a brown base color almost always points towards C. crassiuscula.

Scales brushed from terminal end of abdomen in males of C. erechtea and C. crassiuscula
Range
coast to coast in United States and adjacent parts of Canada; in the west to Northwest Territories, Yukon, and Alaska
Habitat
fields, roadsides, waste places; adults are active day and night, and are attracted to light
Season
adults fly from March to November
Food
larvae feed on clover, grasses, and lupines
Remarks
Due to the similarity in spelling, the genus Caenurgina is sometimes confused with Caenurgia, a genus in the same subfamily and tribe as Caenurgina.
