Natural History

Behavior

Hunts by gleaning prey from vegetation instead of catching it in flight like other darners. Will catch prey, including smaller dragonflies and take them to a perch to feed. Because of this unique hunting style they are not usually found in feeding swarms like other species. May forage until dusk.

Habitat

Forested swamp, lakes, ponds and slow moving streams. Usually border by bushes and trees

Reproduction

Females lay eggs by themselves in rotting wood and submerged logs below and above the water. Can lay eggs almost a foot above the water line
