Hematophagy (sometimes spelled haematophagy or hematophagia) is the practice by certain animals of feeding on blood (from the Greek words αἷμα haima "blood" and φαγεῖν phagein "to eat"). Since blood is a fluid tissue rich in nutritious proteins and lipids that can be taken without great effort, hematophagy is a preferred form of ...
The female Triatoma sanguisuga typically lays eggs four to six days after a blood meal. One female may lay hundreds of eggs in its lifetime. After the egg hatches, the immature bug takes a blood meal and molts eight times before reaching maturity. Triatoma sanguisuga feeds on blood from mammals such as raccoons, rats, dogs, cats, and humans. In ...
The members of the Triatominae / t r aɪ. ə ˈ t ɒ m ɪ n iː /, a subfamily of the Reduviidae, are also known as conenose bugs, kissing bugs (so-called from their habit of feeding from around the mouths of people), [1] or vampire bugs. Other local names for them used in the Americas include barbeiros, vinchucas, pitos, chipos and chinches.
Its reservoir is in wild animals but its vector is a kissing bug. This is a contagious disease and can be transmitted through a number of ways: congenital transmission, blood transfusion, organ transplantation, consumption of uncooked food that has been contaminated with feces from infected bugs, and accidental laboratory exposure.

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] Grass assassin bugs – genus Lopodytes
In particular, dogs in larger holdings, young animals, dogs in contact with other animals, hunting dogs, strays, and animals fed raw meat products are at higher risk of infection. [69] The European Scientific Counsel Companion Animal Parasites (ESCCAP) - the European association of experts on parasites in dogs and cats - has therefore issued ...
Most of the parasitic mites do not feed directly on blood, but the dermanyssid mites and larval trombiculid mites directly suck up capillary blood as their exclusive food. The tube through which food is ingested and saliva excreted during feeding is formed in most mites by apposing the sheath that contains the chelicerae against the hypostome.
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 ...
