Euxoa flavicollis

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

SeasonalityAdults have been collected in Alberta from early July through mid August. IdentificationA medium-size (3.0-3.4 cm wingspan) moth with dark brown forewings, with a pale yellow-brown, ochre or dull orange costa. The cubital vein is shaded with white scales for the same distance. The dark filled orbicular and kidney-shaped reniform are relatively small and outlined in the same pale yellow or orange scales. There is a narrow yellow or orange streak beyond the claviform spot. The hindwings are suffused with sooty or brown scales, darkest towards the outer margin. The basal half of the prothoracic collar is the same pale yellow or orange (in some females silver-grey) color as the costa, and this character alone will separate flavicollis from the similar Euxoa ridingsiana. E. flavicollis belongs to the subgenus Orosagrotis; keys to the subfamilies and species in each are provided in Lafontaine, 1987.

Life History
Poorly known, with the immature stages known only from lab rearings. There is a single brood each year. There is apparently a relatively short period of aestivation prior to the larvae pupating. Adults are nocturnal…
Poorly known, with the immature stages known only from lab rearings. There is a single brood each year. There is apparently a relatively short period of aestivation prior to the larvae pupating. Adults are nocturnal and are attracted to light.
Conservation A relatively common, widespread species; no concerns. Diet Info Unknown. Probably a general feeder of low herbs like most members of the genus. Range
Southern Northwest Territories south in the mountains and Great Plains to North Dakota, Colorado, Utah and southern Washington. In Alberta it has been collected from the Red Deer River badlands north to Edmonton and…
