Bedbug
Donald J. Borror 

Bedbugs, family Cimicidae, order Hemiptera, are flat, broadly oval, wingless bugs about 0.6 cm (0.24 in) in length that feed by sucking blood from birds and mammals.

The common bedbug that attacks humans is Cimex lectularius, which is often a pest in houses, hotels, military barracks, and other living quarters; it also attacks animals.

This insect is usually nocturnal, hiding in cracks and
crevices during the day. The adults may live several months and can survive long periods without food. Bedbugs inflict irritating bites; they are not known to cause disease.
