This is a dissected, male C. erechtea. Note the mouse gray color and the AM dark area that does NOT touch the inner margin of the forewing.

Scales brushed from terminal end of abdomen in males of C. erechtea and C. crassiuscula
Range
Absent from the following parts of Canada where C. crassiuscula occurs: Newfoundland, New Brunswick, Prince Edward Island, Yukon, Northwest Territories.
Otherwise, occurs coast to coast in United States and adjacent parts of Canada.

Fields, roadsides, waste places; adults are active day and night, and are attracted to light.
Season

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.
