PUPATION SITE PREFERENCE AND ENVIRONMENTALLY CUED PUPAL COLOR DIMORPHISM IN THE SWALLOWTAIL BUTTERFLY PAPILIO POLYXENES FABR (LEPIDOPTERA, PAPILIONIDAE)

Environmentally cued polymorphisms are hypothesized to evolve when the environment is coarse-grained and different genotypes are unable to c hoose the habitats in which they are most fit. In Papilio polyxenes, w hich has an environmentally cued pupal colour dimorphism, there is gen etic variation in both tendency to produce brown or green pupae and pr eference for green- or brown-inducing pupation sites, but the two trai ts are not correlated.
