Oncocnemis chalybdis

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

IdentificationA medium-size (3.2 - 3.5 cm wingspan) grey, black and white moth. Forewings blue-grey, crossed by a wide, sharply defined median band, strongly curved on the basal side, less so on the distal. There is also a narrower diffuse black subterminal band and black shading near the wing base and terminal area. Hindwings white with a broad black terminal band. Body black except for the narrow white collar. Oncocnemis chalybdis cannot be mistaken for any other Alberta moth except the closely related O. piffardi Wlk., which replaces it east of the mountains. The white or partially white collar as well as the lack of a swollen base of the male clasper can be used to separate chalybdis from piffardi.

Life History
Adults are nocturnal and come to light. There is a single annual brood, with Alberta adults in late summer and fall (Aug. 10 through Sept. 30). The larvae feed on species of Spiraea, including S. douglassi (Troubridge…

Oncocnemis chalybdis was only recently described as a species separate from O. piffardi, and Bowman's records of piffardi from the mountains and the Calgary area actually refer to chalybdis. BC records of piffardi
Oncocnemis chalybdis was only recently described as a species separate from O. piffardi, and Bowman's records of piffardi from the mountains and the Calgary area actually refer to chalybdis. BC records of piffardi (Jones 1e951) undoubtedly also refer to chalybdis. Bowman lists Zone 21 (Jasper region) as a locality for "piffardi". His collection contains a specimen of chalybdis from Nordegg, which he does not list, but none from Jasper.
