Natural History

Behavior

The Lake Emerald is a strong flier that flies extremely fast and rarely stops to hover. Because of their size and the speed at which they fly they often appear more like a Cruiser than an Emerald They spend most of their time hunting over the open waters, rarely flying close to the shoreline except when mating.

Habitat

Lakes, boggy lakes and large slow moving rivers

Reproduction

Mating typically takes place in the woods. Females lay eggs alone by flying in wide circles, often near an outlet, and dipping there abdomen every few feet
