title: Genetic and environmental effects on wing polymorphisms in two tropical earwigs (Dermaptera: Labiidae).
abstract: The tropical earwigs Paralabella dorsalis and Pseudomarava prominensis are polymorphic for wings in both sexes. An individual's chances of being winged are influenced by whether its parents were winged, by its own sex, and by its nymphal nutrition (at least in P. dorsalis). Wingless females of P. dorsalis lived longer, started ovipositing ealier, and laid slightly larger clutches.
