Abstract
Kukalová-Peck has provided evidence that insect wings evolved from primitively moveable exite lobes of leg podomeres proximal to the coxa. Reinterpretation of previous experimental findings suggests that this hypothesis, as currently formulated, is only partly correct. The costal–subcostal field is derived from an epicoxal exite, but the radial–medial and cubital–anal fields of the wing have arisen from epicoxal endite and (or) subcoxal exite and endite lobes. Wings thus have a complex origin: limb exite plus endite.
