The prothorax is notably elongated and mobile, giving the group its common name of snakefly. The three pairs of legs are similar in size and appearance. The two pair of dragonfly-like wings are similar in size, with a primitive venation pattern, a thickened leading edge, and a coloured wingspot, the pterostigma. Inocelliids lack a cross vein in ...
Psychodidae, also called drain flies, sink flies, filter flies, [2] sewer flies, or sewer gnats, is a family of true flies. Some genera have short, hairy bodies and wings, giving them a "furry" moth-like appearance, hence one of their common names, moth flies . [ 2 ]
The adults are called drone flies because of this resemblance. In its natural habitat, E. tenax is more of a curiosity than a problem. Like other hover flies, they are common visitors to flowers, [12] especially in late summer and autumn, and can be significant pollinators. They often feed on the flowers of carrot and fennel.
Tsetse flies have an arsenal of immune defenses to resist each stage of the trypanosome infectious cycle, and thus are relatively refractory to trypanosome infection. [67] Among the host flies' defenses is the production of hydrogen peroxide, [68] a reactive oxygen species that damages DNA. These defenses limit the population of infected flies.
Fannia spp. (latrine flies) Eristalis tenax (rat-tailed maggots) Muscina spp. The adult flies are not parasitic, but when they lay their eggs in open wounds and these hatch into their larval stage (also known as maggots or grubs), the larvae feed on live or necrotic tissue, causing myiasis to develop. They may also be ingested or enter through ...
Duke Health is a trial site for a drug that could be the first universal antivenom to treat any kind of snake bite — including North Carolina’s ubiquitous copperhead.
Empididae is a family of flies with over 3,000 described species occurring worldwide in all the biogeographic realms but the majority are found in the Holarctic.They are mainly predatory flies like most of their relatives in the Empidoidea, and exhibit a wide range of forms but are generally small to medium-sized, non-metallic and rather bristly.
Adults of the Dolichopodidae live largely in grassy places and shrubbery. The flies occur in a wide range of habitats, near water or in meadows, woodland edges and in gardens. Some groups are confined to wet places including sands on the banks of water bodies; examples include genera such as Porphyrops, Tachytrechus, Campsicnemus, and ...
