aberrans

**Chrysops aberrans**				Reference
This is the most common deer fly in Russell, with a late flight season similar to C. univittatus. It is an annoying man-biting species found in southeastern Ontario and Quebec, with a disjunct population in New Brunswick, and a wide distribution in the northern USA. Larval habitats are permanent ponds and lakes, as well as cattail marshes (Teskey, 1990).

C. aberrans is only mentioned in one study conducted in Ontario, where it accounted for 0.9% of the catch at Caledonia (Troubridge & Davies 1975). It was also a minor component of the catch at Trois Rivi�res, Quebec (Baribeau & Marie, 1983). In contrast, it was the most common tabanid at Lake Lansing Park-North in Michigan (Strickler & Walker, 1993), and was one of the most abundant species near Lac Boivin at Granby, Quebec (Leprince & Lewis, 1982). It is present, but rare in New Brunswick (Lewis & Bennett, 1977; Thomas, 1980). Small numbers have also been recorded in surveys conducted in New Jersey (Thompson, 1969), Connecticut (Magnarelli & Anderson, 1981) and Rhode Island (Bartlett et al., 2002). Teskey (1969) and Pechuman (1981) provide information on the biology of immatures and their habitats.
