Note on Aedes melanimon Dyar, a Mosquito New to Canada (Diptera: Culicidae)

Abstract

Four males of Aedes melanimon Dyar were collected in mosquito traps during flight studies on the prairie near Brooks, Alberta, in 1956. One of the specimens was taken on July 14, and two on July 24; the collection date of the fourth specimen is unrecorded. The determinations were made by Dr. J. R. Vockeroth, Entomology Division, Ottawa, from preparations of the genitalia. This is the first time that this species has been recorded from Canada; it was previously known only from the western United States. It is possible that females of this species have been collected in Canada but have not been recognized because of the similarity to A. dorsalis (Meig.). Barr (1955) and Richards (1956) have reviewed the specific status of Aedes melanimon Dyar and compared the morphology of this mosquito with that of other closely related species.
