Polymorphism in Plastosciara perniciosa

Two widely divergent morphotypes of both adult males and adult females were found in laboratory colonies of Plastosciara perniciosa in Hawaii. Extraordinary modification of all features except the genitalia, with associated behavioral differences, enables the micropterous morphotype to take maximum advantage of a stable larval habitat. Capabilities for migration from adverse habitats, dispersal, and maintenance of gene flow are retained in the macropterous morphotype.
