Dragonhunter
Hagenius brevistylusAlso known as Dragon Hunter
As North America's largest clubtail dragonfly, the dragonhunter is a formidable aerial predator that routinely catches and consumes other dragonflies, butterflies, and bees in midair. Adults spend sunny afternoons perched on exposed logs or riverbank branches, keeping a watchful eye over rocky forest streams. Their aquatic nymphs are equally distinctive, living for several years on the riverbed as flattened, leaf-like hunters before emerging.
