Chrysops viduatus is a species of horse fly belonging to the family Tabanidae. [3]
It is a Palearctic species with a limited distribution in Europe [4]
The middle tibiae of C. viduatus are distinctly yellow-brown. The second abdominal segment is yellow with a well-defined quadrate black spot.
Chrysops viduatus occurs in wet meadows, mires, fens and wet woodlands. The larvae feed on organic matter in wet peaty detritus. Adults feed on large mammals including cattle, horses and deer.
Horse-flies and deer flies are true flies in the family Tabanidae in the insect order Diptera. The adults are often large and agile in flight. Only female horseflies bite land vertebrates, including humans, to obtain blood. They prefer to fly in sunlight, avoiding dark and shady areas, and are inactive at night. They are found all over the world except for some islands and the polar regions. Both horse-flies and botflies (Oestridae) are sometimes referred to as gadflies.
Deer flies are bloodsucking insects considered pests to humans and cattle. They are large flies with large brightly coloured compound eyes, and large clear wings with dark bands. They are larger than the common housefly and smaller than the horse-fly. There are 250 species of deer fly in the genus Chrysops. Their distribution is worldwide, though they have not been reported in Iceland, Greenland, or Hawaii.
Chrysops niger, the black deer fly, is a fly of about 8–10.5 millimetres (0.31–0.41 in) length, with a mostly black body with some white hairs, and having wings which are barred with black. They are active from May to September around areas of marsh.
