For example, Diptera insects with two wings, such as flies have eleven families with hematophagous habits more than half of the 19 hematophagous arthropod taxa. To overcome natural hemostasis blood coagulation , vasoconstriction , inflammation, and pain sensation in the host, hematophagous animals have evolved hembiochemical solutions, in their saliva for instance, that they pre-inject—and anesthesia and capillary dilation have evolved in some hematophagous species. Some doctors now use leeches to prevent the clotting of blood on some wounds following surgery or trauma.
