Comments.

Stethusa spuriella appears to be a common species in both forested and open habitats in Ontario. No Canadian specimens of the third eastern species, Stethusa dichroa (Gravenhorst), were discovered in our material despite its widespread occurrence in the eastern United States; it is expected to occur in southern Ontario.
