Dromogomphus spinosus (Black-shouldered Spinyleg)Large, fairly obvious and among the more cosmopolitan Gomphidae species in Vermont. Fairly broad distribution probably correlates to ability to breed in varied habitat – mostly larger streams and slow rivers as well as lakes with rocky shorelines. The Connecticut River (Hunt et al.) and Poultney River basin seems to be strongholds for this species, our only member of this sparse genus in Vermont. Can be found perched on lakeside vegetation and riverside boulders or tenaciously patrolling a small section of territory along a river.
