Species Details

Dysstroma walkerata

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

SeasonalityAdults fly in Alberta mid to late July. IdentificationThis group of Dysstroma, consisting of D. citrata, suspectata, walkerata,and truncata, form a complex of species which are often difficult to distinguish without resorting to genitalic characters. D. walkerata is often confused with D. truncata (the two were once considered to be conspecific) or suspectata. D. walkerata is on average the largest of our Dysstroma, with well-defined, relatively pale orange-brown AM and PM bands. It lacks the white flush often seen in D. citrata and truncata, and has a less mottled appearance than citrata and truncata. McDunnough (1946) illustrates the male and female genitalia.
