what animals suck blood
Bed Bugs. Bed bugs are blood-feeding insects (Figures 1â3) that feed mainly on the blood of humans, but also suck blood from other animals, such as birds, bats, and rodents. Bed bugs usually feed at night when people are asleep because the hosts are unaware that they are being fed upon.
Mosquito mouthparts are very specialized, particularly those of the females, which in most species are adapted to piercing skin and then sucking blood. Apart from bloodsucking, the females generally also drink assorted fluids rich in dissolved sugar, such as nectar and honeydew, to obtain the energy they need.
