Cucullia speyeri is a noctuid found in North America, ranging from the Canadian prairies to the Atlantic coast. The species inhabits open, dry grassland and meadow . are active in late spring and summer, with a wingspan of approximately 48 mm. The larvae feed on herbaceous Asteraceae and Conyza species. In Connecticut, the species is listed as a species of special concern and is believed to be extirpated.

Identification

Members of the Cucullia can be recognized by their distinctive hooded forewing shape with a convex costal margin. Within the genus, C. speyeri can be distinguished from similar North American by its specific geographic distribution and association with dry grassland and prairie . Detailed morphological distinctions from closely related such as C. asteroides or C. intermedia are not documented in available sources. Dissection of genitalia is typically required for definitive species identification in this genus.
