in the eastern United States harbors locally dense populations of two ''Axarus'' species, both currently undescribed. These populations are interesting in that they are restricted to specific larval habitat (
varve clay and sometimes rotting wood) and thus there is genetic structure between populations in the river . The Connecticut River species are also notable in that they have extremely well developed
polytene chromosomes and also maintain a high degree of
