This “common bedbug" Cimex lectularius, uses its mouth parts adapted to piercing skin in order to obtain its blood meal.

The bedbug gets its name from the fact that it often makes its home in and around a bed, in the mattress, box spring, and even the bed frame itself. It feeds at night while its host sleeps, and can obtain its blood meal in as little as 3 minutes.
