|Description:||This image depicts a close dorsal view of the head and thorax of an adult, Cimex lectularius bed bug.|
Adult bed bugs are on average 5 mm long, oval-shaped and dorsoventrally flattened. Like other members of the order, Hemiptera, they possess piercing-sucking mouthparts. Adults are brachypterous, which means that the hindwings are nearly absent, and the forewings are reduced to small, leathery pads. Note in PHIL 12704, nymphs look like smaller, paler versions of the adults.
