Adults eat wasps,butterflies, mosquitoes and other flyinginsects (including other dragonflies).Predators: Larvae are eaten by fish, turtles, frogsand wading birds. Adults are eaten bybirds, fish and frogs.Sexual maturity: Two to three months after emerging asadult dragonfliesEggs: Laid one at a time in aquatic vegetationIncubation: The eggs hatch in the spring.Young: During the larval stages, generally lastingtwo to three years, the nymphs(aquatic larvae) pass through 11 to 12larval stages before metamorphosinginto dragonflies. Once they emerge asadults, they immediately begin the cycleagain.Life span: A few years in larval form, only four toseven weeks as adultsHABITATCommon green darners prefer permanent and temporary ponds,lakes, bays, estuaries and slow-moving streams and riparianareas (land adjacent to a body of water).BEHAVIORDuring the reproductive stage, the common green darner seeksfresh water ponds. Males return first, then females who havealready developed a batch of eggs. If the female is receptive,mating begins. They often mate in flight. Immediately after mating,common green darner females lay their eggs, one at a time,in tiny slits in submerged aquatic plants. Males work hard toprotect their territories. Some have been clocked chasing intrudersaway at 35 miles per hour. Common green darners are oneof the few dragonflies that migrate in the spring and fall.Scientists believe that they migrate with seasonal warm fronts.NOW YOU KNOW!• Most of a dragonfly’s brain is dedicated to processing andresponding to what they see. Their complex eyes providenearly 360-degree vision.• Dragonflies can hover like a helicopter.• They can exchange oxygen through specially adapted analchambers.COMMON GREEN DARNERSAND PEOPLECommon green darners are called “mosquito hawks” becausethey eat mosquitoes, providing an important service to humans.As an animal that lives in both freshwater and terrestrial (land)habitats, having healthy green darner populations indicates abalanced and healthy ecosystem.PWD LF D0200-848D (8/02) NOTICE: Texas Parks and Wildlife Department receives federal financial assistance from the U.S. Fish and Wildlife Service.
