Many species of flies of the two-winged type, Order Diptera, such as mosquitoes, horse-flies, blow-flies and warble-flies, cause direct parasitic disease to domestic animals, and transmit organisms that cause diseases. These infestations and infections cause distress to companion animals, and in livestock industry the financial costs of these ...
The flies are pool feeders. Their saliva, which contains anticoagulants, a number of enzymes and histamine , is mixed with the blood, preventing clotting until it is ingested by the fly. These bites cause localized tissue damage, and if the number of feeding flies is sufficient, their feeding may produce a blood-loss anaemia .
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.

In long-coated animals, matts and burrs can cause irritation which leads to hot spots , scratching, open lacerations, and infestation.
This makes the horn fly genome larger than the genome sizes of the related Muscidae flies Musca domestica and Stomoxys calcitrans, which were reported as 1.0 Gb and 1.1 Gb. [ 10 ] [ 11 ] In addition to the nuclear genome of the Kerrville reference strain, the maternally inherited endosymbiont Wolbachia pipientis w Irr has also been assembled.
