Tumidagena
Tumidagena is a genus of small, flightless delphacid planthoppers comprising at least three described species. The best-studied species, T. minuta, is a specialist herbivore of the salt marsh grass Spartina patens in eastern North America. Despite being predominantly flightless (>99% of adults), populations exhibit high gene flow and weak genetic differentiation over distances exceeding 400 km, suggesting mechanisms other than adult flight maintain connectivity.
