Euxoa dargo

University of Alberta E.H. Strickland Entomological Museum Read more about this collection »

SeasonalityAdults have been collected in Alberta from mid August through mid September. IdentificationA medium-sized (2.7-2.9 cm wingspan) moth with dark brown head, thorax and forewings and lighter grey-brown hindwings. The forewing ground is dark grey brown, with the costa, orbicular and reniform spots and subterminal line contrasting light buff. There is a pale streak just beyond the claviform. The cubital vein is finely lined with white scales, and crosses the subterminal line into the darker subterminal area. The fringe is brown with a buff base. The hindwings are dirty white, with a prominent discal dash and broad, rather sharply defined dull grey-brown terminal band and white fringe. Similar to E. niveilinea. The prominent pale streak on the lower forewing will separate dargo from E. niveilinea. The saccular extensions of dargo are not much longer than the harpes, but almost twice as long in niveilinea. E. dargo belongs to the detersa group of the subgenus Euxoa. Keys to the group, subgenus and species are provided in Lafontaine 1881 and 1987.
