Wing shape differences along a migration route of the long-distance migrant Globe Skimmer Dragonfly Pantala flavescens

Abstract Animals which migrate by flying should be subject to selection for optimal wing characteristics that maximize energy efficiency during migration. We investigated shape and area variation in the Globe Skimmer Dragonfly Pantala flavescens , has longest known migration of any insect. Wing differences between individuals southern Peninsular India, migrating at a stop-over site on Maldives, were compared. Results suggest successfully reached their way from India Africa, had broader base an overall more slender than India. Contrary our expectations, did not differ significantly most comparisons suggesting is important successful P. . The results provide indirect evidence natural dragonfly.
