Prokelisia
delphacid planthoppers
Prokelisia is a genus of delphacid planthoppers in the family Delphacidae, containing approximately five described species. The genus is best known for P. marginata, a salt marsh specialist that exhibits striking wing dimorphism with flightless brachypter and fully winged macropter forms. These planthoppers feed on Spartina cordgrasses and serve as hosts for diverse parasitoid communities including egg parasitoids (Anagrus spp.), nymphal parasitoids (Gonatopus, Neon), and adult parasitoids (Eurypteryx). The genus has become a model system for studying the evolution and maintenance of dispersal polymorphisms in heterogeneous environments.
