Cimex lectularius, the common bedbug, hides in cracks and crevices in furniture, floors and walls and comes out at night to feed on its favorite meal, human blood. It grows up to 0.3 inches (7 millimeters) long and can live up to one year. The tiny hairlike structures shown on the back of this bedbug are not actually hairs but sensory structures called setae, according to the CDC.
