Identification

Characteristics of true bugs

Gradual or incomplete metamorphosis (no pupa stage)

Juveniles (nymphs) resemble adults, but may vary in coloration, and usually have reduced wings which become larger in successive molts

Soft or hard-bodied, often dorsoventrally flattened in profile

Typically two pairs of wings in adult: forewings (hemelytra) are partly thick and protective, and partly membranous

Hindwings are typically fully membranous and function in flight, though some species are wingless. (Juveniles have reduced wings.)

Wings at rest have apical portion (tip) crossed - a distinctive characteristic

Scutellum (triangular portion of thorax exposed between base of wings along midline) is prominent. Beetles may also have a prominent scutellum.

Mouthparts are a piercing or sucking "beak" arising from front of head

Antennae, when not hidden, have 4-5 segments

Ocelli (simple eyes) present in some groups

Some groups such as stink bugs (family Pentatomidae) have thoracic scent glands whose secretions are for defensive purposes
