INTRODUCTION
Polyphenism is the occurrence in a population of alternative phenotypes that are produced from a single genotype in response to different environmental stimuli (West-Eberhard 1989). Organisms that exhibit polyphenism provide an excellent arena for examining the mechanistic and functional bases of phenotypic variation because the variation is discrete and easily manipulated. Also, polyphenism often results in expression of the phenotype most advantageous under current environmental conditions, thereby facilitating an examination of the fitness consequences of different phenotypes (West-Eberhard 1992).
