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 ...

Triatoma is a genus of assassin bug in the subfamily Triatominae (kissing bugs).

Their saliva may also trigger allergic reactions in sensitive individuals, up to and including severe anaphylactic shock. [1]
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.
"Only fertilized female mosquitoes will suck blood, because they need proteins to make their eggs develop. Males and unfertilized females will eat some nectar from plants. And some males do not ...
Asian lady beetles are more aggressive than ladybugs and they will bite humans or animals if provoked. Unlike mosquitos, these beetles don't suck blood, so biting is only a defense mechanism. They ...
