SeasonalityThere is a single annual brood with adults collected in Alberta in late June and late July. Nothing is known of the early stages. IdentificationAnother medium-size (approx. 2.8 cm wingspan) mottled grey Xanthorhoe species with a darker grey forewing median band, widest and darkest on the upper half. It is similar to incursata, ramaria, fossaria, and delectaria species, and cannot be reliably separated from incursata and delectaria without examining the genitalia.

The group of Xanthorhoe that contains macdunnoughi is one of the most difficult groups of Alberta macrolepidoptera to identify using superficial characters. Fortunately the genitalia (male valve illustrated above) has excellent characters for identifying macdunnoughi. This group has never been revised and a revision is badly-needed. The illustrated specimen was collected in the Crowsnest Pass in 2001 by C. D. Bird.
