moechus

*Chrysops moechus*				Reference
Relatively few individuals have been captured to date. C. moechus is found in eastern Ontario, southern Quebec and southern Manitoba; it is more widely distributed in the eastern USA. Larval habitats are associated with streams (Teskey, 1990).

Literature on this species is minimal; its biology appears to be documented only in taxonomic references. Teskey (1960) in Ontario, and Baribeau & Maire (1983) in Quebec appear to have captured only single specimens. In New Jersey, C. moechus represented only 0.7% of the tabanid catch in Malaise traps, and 0.4% of the catch in aerial netting (Tallamy et al., 1976). Small numbers were caught in Rhode Island (Bartlett et al., 2002). At Caledonia in Ontario, it represented 1.1% of the tabanid catch in pyramid traps (Troubridge and Davies, 1975). These authours dissected 331 flies, of which 13.3% were uniparous, with no biparous flies. Parous flies were mostly recorded a month or more after the species was first caught, consistent with oviposition requiring a blood meal. Pechuman (1981) and Teskey (1969) provide information on the biology of immatures and their habitats. The species has been recorded as far south as Texas (Goodwin & Drees, 1996).
