Abstract

Adults of Zonocerus variegatus (L.) from the dry-season population in southern Nigeria were shown to exist in two forms, one with relatively long wings and the other with relatively short wings. The wet-season population normally existed as the short-winged form, but the insects had the capacity to develop long wings. Long-winged insects had welldeveloped flight muscles and were capable of flight. Flight in the field occurred before sexual maturation and may have led to downwind displacement of individuals over considerable distances.
