Family Overview
Gomphidae

Clubtails
This family includes approximately 16 genera and more than 80 North American species. This is a fairly common and widespread group, found among debris or burrowing in both lentic and lotic habitats. Nymphs are easily identified by their rather thick antennae. Like other dragonflies, the adults and nymphs are predators. Nymphs bury in the sediment, partially hiding themselves to wait for prey to pass by, and then snatch them up with their arm-like labral mask. The adults typically fly low to the ground and only in bright sun.
