Dragonflies belong to the Odonata order. It is characterized by very large mutifaceted eyes, two pair of strong transparent wings and elongated wings. Dragonflies are similar to damselflies, but the adults can be differentiated by the position of their wings while resting. Dragonflies’ wings are held to the side and perpendicular to the body while the damselflies held their wings in verticle position.
Dragonflies usually has a life span of more than a year. The adult dragonflies mate in the air. After them mate, the female dragonflies lay eggs on the plant in the water. If they can’t find a suitable plant, they will just drop them in water. The nymph stage begin after the egg hatches. Dragonfly lives in the water while they grow and developed into dragonfly. The nymph stage can take up to four years to complete. The dragonfly nymph will come out of water and turn into adult, once the dragonfly nymph fully grown and the temperator is warm. They will hunt and start to mate. The adult stage typically lasts less then two month.
You should not have trouble finding in near by pond during summer since dragonflies are aquatic insects. We collected a Eastern Amber Wing dragonfly (Perithemis tenera) near a pond at little mulberry park located in Dacula, GA, USA on Jun 26, 2010.
