A total of 11 111 specimens were collected, representing 41 families and 438 species. A species list with flight times is presented. The total Lepidoptera community was estimated to be 546 ±23.34 species. Abundance and species richness peaked in late July. Thirty-five species constitute new records for Alberta, while one species. Acanthopteroctetes bimaculata, is a new record for Canada, and the first record of the family Acanthopteroctetidae in Canada.
