Horse Flies and Deer Flies (Diptera: Tabanidae) Feeding on Cattle in Southwestern Quebec

“…Tabanus quinquevittatus Wiedemann was the most abundant species (Table I), accounting for 74.5% of the total specimens collected. It is a severe pest of horses and other livestock in New York (Jamnback 1969;Pechuman 1972) where it is the most abundant tabanid in some areas (Matthysse et al 1974).…”

“…similis Macquart, yet it comprised only 9.7% of the specimens collected. This species is also a frequent pest of livestock in New York, but is not usually as numerous as T. quinquevittatus (Pechuman 1972). Lewis and Bennett (1977) collected T .…”

“…atratus Fabricius (3.2%), and H. frontalis (Walker) (2.4%). Hybomitra lasiophthalma is a pest of livestock in New York (Jamnback 1969;Pechuman 1972) and Lewis and Bennett (1977) reported that in New Brunswick this species was more frequently collected flying about cattle than any other tabanid. Tabanus atratus is a large (26 mm) black horse fly which is extremely noticeable and annoying when flying about cattle and attempting to feed.…”

“…Tabanus atratus is a large (26 mm) black horse fly which is extremely noticeable and annoying when flying about cattle and attempting to feed. Pechuman (1972) reported that due to its size and loud buzzing while in flight, it is very disturbing to horses and cattle in New York. Chrysops frigidus Osten Sacken, while collected in low numbers in the study area, is the most abundant species of Chrysops attracted to and feeding on livestock in New Brunswick (Lewis and Bennett 1977).…”

“…When alive, most readily separated from the similar vivax by the complete single dark eye-stripe (b); eye stripe a short dash in vivax. Teskey (1990) recorded this species from only 3 localities in Ontario and Pechuman (1964) recorded it from Quebec (no locality data). However, it is widespread in southern New Brunswick in association with fast flowing rivers where larvae occur among stones and gravel.…”
