Wing polymorphism commonly occurs in many insects, especially species of Orthoptera, Coleoptera, Homoptera, and Hemiptera (Harrison, 1980). The polymorphism consists of discrete differences in wing length with morphs exhibiting fully developed, reduced, or totally absent wings. In addition to differences in wing length, morphs often differ in a number of other characteristics such as degree of flight muscle development, duration of nymphal development, time to first reproduction, fertility and diapause (Anderson, 1973; Vepsäläinen, 1978; Harrison, 1980).
Wing polymorphism is an attractive system for investigating the evolution of dispersal in natural populations (Vepsäläinen, 1978; Denno and Grissell, 1979; Harrison, 1980). A …
