| Abstract: | Males of 17 species of Chrysops, Hybomitra and Tabanus (some of them economic) were collected on the summit of Mount Rigaud in south-western Quebec, Canada. Male flight activity lasted from late May to late August, and the greatest species diversity occurred in mid-June. Males of each species were more abundant than females and usually had a longer seasonal distribution. Observed premating behaviour comprised hovering in the air and waiting on plants. Nectar was found (by cold anthrone tests) in 73% of the males, including 43% of waiting and 84% of hovering males. The commonest pollen grains observed on males of H. sodalis (Will.) came from nectar-bearing plants with large inflorescences. Sunlight stimulated male activity when the temperature was suitable for flight. |
