Status:

Cobra Clubtail (Gomphurus vastus) generally inhabits medium-sized creeks up to large rivers with silt or sand substrate. This species appears darker in flight than several similar species, and has a proportionately wide club, befitting its common name (Paulson, 2011). In Maryland, Cobra Clubtail is considered uncommon on the Susquehanna and Patapsco drainages, while it is common along the Potomac and larger tributaries (Richard Orr's The Dragonflies and Damselflies of Maryland and the District of Columbia).

There are 118 records in the project database.
