Abstract

Populations of the butterfly Euphydryas editha differ in dispersal rates of component individuals. We give evidence that these differences are at least partly genetically based and are the result of long-term selection pressures associated with the detailed ecology of each population. Within this framework, population structure is affected by the distributions of larval and adult resources in space and time, and is described in detail for two populations of contrasting types. We predict genetic consequences of interpopulation differences in dispersal and use our observations of E. editha to illustrate a general discussion of factors affecting dispersal in insects.
