Natural History

Behavior

Common Whitetails are usually pretty easy to find. They often perch out in the sun on the ground, logs, rocks or other flat surface. They hunt small insect in flight, ambushing them from the ground or a low perch. Males are extremely territorial and will chase any male Whitetail or similar looking species out of their territory

Habitat

Lakes, ponds, pools, marshes, slow moving streams. They prefer muddy bottoms.

Reproduction

Reproduction is quick, lasting only seconds, and happens in flight. Females can lay up to 1000 eggs per day by slapping their abdomen on the surface of the water while the male hover guards. Other males often attempt to sneak in and mate with the female while she is laying since it is the last sperm packets deposited that are used to fertilize the eggs
