Once phlebotomy is performed (in most insects by a specialized fine hollow "needle", the proboscis, which perforates skin and capillaries; in bats by sharp incisor teeth that act as a razor to cut the skin), blood is acquired either by sucking action directly from the veins or capillaries, from a pool of escaped blood, or by lapping (again, in ...
Chagas disease is a modern-day tropical disease caused by Trypanosoma cruzi and transmitted by kissing bugs, so-called because they suck human blood from around the lips while a person sleeps. [92] The bed bug, Cimex lectularius, is an external parasite of humans. It lives in bedding and is mainly active at night, feeding on human blood ...
In feeding on blood, the flies use their mouthparts to initiate bleeding from the host. They then suck up the exposed blood. Like practically all blood-feeding parasites, they inject biochemicals that inhibit blood clotting, plus some that stimulate host mast cells to produce histamine; this distends capillary vessels, thereby promoting blood flow.
Fleas are wingless insects, 1.5 to 3.3 millimetres (1 ⁄ 16 to 1 ⁄ 8 inch) long, that are agile, usually dark colored (for example, the reddish-brown of the cat flea), with a proboscis, or stylet, adapted to feeding by piercing the skin and sucking their host's blood through their epipharynx. Flea legs end in strong claws that are adapted to ...
Don't let the bed bugs bite. The tiny, blood-sucking insects are preparing for some feasts as summer—when they're most active— and peak travel season approaches.
Haematosiphon inodorus is a species of blood-sucking obligate ectoparasitic insect from the family Cimicidae, commonly called Mexican chicken bug, chicken bug or poultry bug. After feeding they remain in or near their host's roost, nest, substrate, or dwelling, but not on the body.
Most of the 130 or more species of this subfamily feed on vertebrate blood; a very small portion of species feed on invertebrates. [2] [3] They are mainly found and widespread in the Americas, with a few species present in Asia and Africa. These bugs usually share shelter with nesting vertebrates, from which they suck blood.
Kissing bugs (or cone-headed bugs) – subfamily Triatominae, unusual in that most species are blood-suckers and several are important disease vectors Wheel bugs – genus Arilus , including the common North American species Arilus cristatus [ 2 ] [ 3 ] [ 4 ]
