This image depicts a dorsal view of a nymphal, Cimex lectularius bed bug. Once it attains adulthood, it will measure, on average, 5mm in length. It will assume an oval shape, and be flattened in its dorsoventral dimension. 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. Nymphs look like smaller, paler versions of the adults, an example of which can be seen in PHIL 12704.
