Gomphus abbreviatus (Spined-crowned Clubtail)Small and stocky, known from only a few sites in western Rutland County (Poultney and Hubbardton rivers) and one site on the Connecticut River below Vernon Dam. With limited data, and variability in each known site, habitat preferences in Vermont would be difficult without additional encounters. Can be locally common, with collection of exuviae during early stages (late May) of its flight period the most reliable survey method. One speculation: although egg-laying appears to be in riffle areas, larvae may drift downstream into silty areas for emergence.
