Gomphus adelphus (Mustached Clubtail)One of Vermont’s two members in the subgenus Hylogomphus. Far less common and widespread than most members of the genus, it has a scattered and somewhat unpredictable distribution on rivers of varying sizes. Nevertheless, new sites for this species seem to be gradually turning up, so gaps in its distribution may begin to close. Sites range from rocky, swiftly flowing rivers to small pond outlets. May also breed along rocky shores of Lake Champlain.

Status: G4 N4 S3
