The blowfly traps contain a liquid that smells like the rotting flesh of a carcass and the structure of the trap is designed to prevent the flies from escaping once attracted in. [1] [60] Horse-flies can be controlled by traps that attract the flies to a suspended black ball that mimics a potential host; flies attracted become trapped in a cone ...
To obtain the blood, the females, but not the males, bite animals, including humans. The female needs about six days to fully digest her blood meal and after that, she needs to find another host. [5] The flies seem to be attracted to a potential victim by its movement, warmth, and surface texture, and by the carbon dioxide it breathes out. [33]
There has to be abuse or neglect that causes an injury with blood, decaying tissue, feces or urine that attracts flies and the animals must be fairly helpless or incapable of cleaning themselves. In long-coated animals, matts and burrs can cause irritation which leads to hot spots , scratching, open lacerations, and infestation.
Although flies are most commonly attracted to open wounds and urine- or feces-soaked fur, some species (including the most common myiatic flies—the botfly, blowfly, and screwfly) can create an infestation even on unbroken skin. Non-myiatic flies (such as the common housefly) can be responsible for accidental myiasis.
The flies that feed on vertebrate blood have sharp stylets that pierce the skin, with some species having anticoagulant saliva that is regurgitated before absorbing the blood that flows; in this process, certain diseases can be transmitted. The bot flies (Oestridae) have evolved to parasitize mammals.
Female flies require a fair amount of blood for their aforementioned reproductive purposes and thus may take multiple blood meals from the same host if disturbed during the first one. [5] Although Chrysops dimidiata and C. silacea are attracted to canopied rainforests, they do not do their bite there. Instead, they leave the forest and take ...
They can be attracted to various substances including sugar, sweat, tears and blood. Larvae occur in various habitats including decaying vegetation, dry and wet soil, nests of insects and birds, fresh water, and carrion. The housefly, Musca domestica, is the best known and most important species.
Most female horse flies feed on mammal blood, but some species are known to feed on birds, amphibians or reptiles. Other bloodfeeding Diptera are Ceratopogonidae Phlebotominae Hippoboscidae, Hydrotaea and Philornis downsi (Muscidae), Spaniopsis and Symphoromyia Rhagionidae. There are no known acalyptrates that are obligate blood-feeders.
