Deer fly. Chrysopsinae is an insect subfamily in the family Tabanidae commonly known as deer flies or sheep flies and are bloodsucking insects considered pests to humans and cattle. [3] They are large flies with large brightly-coloured compound eyes, and large clear wings with dark bands. [4] They are larger than the common housefly and smaller ...
Nov 30, 2022 · Deer flies, sometimes grouped with horseflies or moose flies, are small flying insects with painful bites found all over the world. This kind of fly is persistent and leaves behind annoying, itchy ...

Deer flies are commonly found in damp environments such as wetlands, ponds, streams, and marshes. They prefer areas with standing water, which is where they lay their eggs. This means that if you’re near a body of water, you’re more likely to encounter deer flies.

The bites of female horse and deer flies are painful and, if numerous enough, can disrupt recreational activities and even the harvesting of some agricultural crops. Their mouthparts include two pairs of cutting "blades" that lacerate skin and cause flow of blood out of the wound, which females lap up with a sponge-like mouthpart. Males have simila...
Horse and deer flies are "true" flies in the insect Order Diptera, and comprise the Family Tabanidae known as "tabanid flies" or "tabanids." There are an estimated 4,300 species of horse and deer flies in the world, approximately 335 of which occur in the continental U.S. Of these, over 160 species are horse flies, and over 110 species are deer fli...
Adult horse and deer flies are relatively large to very large (approximately 0.25 to 1.25 inches long), robust flies with a pair of huge eyes known as "compound eyes." Those of some horse flies have colorful purple or green bands against a blue or yellowish-green background. The mouthparts are large and prominent, projecting downward and forward in...
Similar to all flies, horse and deer flies develop from egg to adult via a process of "complete metamorphosis." This means the last larval stage passes through a non-feeding pupal stage, from which the adult eventually emerges. The summarized life cycle of horse and deer flies begins with the emergence of adults from late spring into summer, depend...
Only female horse and deer flies take a blood meal, and, with rare exception, they feed during the daytime. Unlike numerous other groups of blood sucking flies, female horse and deer flies do not enter structures and thus do not feed on humans indoors. Female horse flies feed primarily on large mammals, including stationary hosts, and they typicall...
Humans generally do not influence horse fly and deer fly development because habitats that support larval development are "natural," including freshwater wetlands, saltwater marshes, and open areas within forests. However, there is one type of habitat associated with human activity that can be a source of horse flies. Larvae and pupae of a few spec...
Controlling horse and deer flies is nearly impossible. The use of insecticides to kill larvae is not an option because the vast majority of species develop in natural habitats in which insecticides cannot be applied due to environmental concerns. Even if they could be used, insecticides would be ineffective in controlling larvae because they are wi...
There is surprisingly little information about horse and deer flies on university and governmental websites. There is, however, a recent textbook (2002) by G. Mullen and L. Durden, Medical and Veterinary Entomology, that includes an excellent chapter devoted to horse and deer flies, covering biology, behavior, and medical and veterinary risk. It al...
Tabanidae are known by a large number of common names. The subfamily Chrysopsinae is known as deer flies, perhaps because of their abundance on moorland where deer roam, and buffalo-flies, moose-flies and elephant-flies emanate from other parts of the world where these animals are found.

Jul 19, 2014 · That said, they aren't unique to New Hampshire by any means--in fact, closely related species are found around the world--but we have at least our fair share of them. Deer flies are closely related to horse flies, both being of the Tabanidae family with deer flies in the genus Chrysops.
