Gomphus descriptus (Harpoon Clubtail)Sparse occurrences in an odd pattern, generally the northeastern and southwestern portions of the state. Inhabits river sites, perhaps favoring sand-bottomed substrates. Rarely found in numbers approaching those of G. borealis or its other more common congeners. Sporadic in the Champlain Valley. G. descriptus may yet prove to have a wider distribution than is currently known. Nevertheless, this species is vulnerable or imperiled across some of its range. Endangered in Massachusetts, it may warrant watching for population or distributional declines in Vermont.

Status: G4 N4 S3
