Digest: Rapid evolution of an annual invader, the African fig fly Zaprionus indianus

Abstract

Little is known about evolutionary dynamics shortly after species introduction. Gray et al. (2025) found that the African fig fly (Zaprionus indianus) evolved smaller wings and a decreased wing: thorax ratio within one season of colonizing a temperate region of the United States, but did not differ along a latitudinal cline. This demonstrates the species' capability for rapid adaptation and potential for enhanced invasiveness.
