Habitat and Range
Habitat
Streams, usually with sandy bottoms and in fairly open areas with little canopy of trees. Often associated with freshwater "eel-grass", e.g., Vallisneria americana , also called wild celery .
Geographic Range
Southeastern United States: Massachusetts and Kentucky south to Florida, eastern Texas. Found largely in the coastal plain on the Atlantic seaboard. Usually found in small colonies because dispersal is limited.
Seasonal Activity
April-September (Georgia). March-September (Louisiana). May-September (New Jersey).
Diet and Behavior
Life History
Male patrols a territory 1-4 meters in diameter near oviposition sites, gives "cross" display, floating on the water over site, then gives rapid wingbeat display during courtship. Female oviposits underwater, usually submerging completely and starting to lay her eggs (160 in each daily bout) at the base of an aquatic plant .
About Dragonflies and Damselflies: the wider group
Order-level background for Odonata, the group containing Calopteryx dimidiata. Species-specific details appear above.
Group overview
Odonata includes ~6,000 described species of dragonflies and damselflies. Dragonflies are among the fastest flying insects, reaching 36 mph (58 km/h). They can fly in any direction including backward, and hover in place - each wing operates independently.
Ecological role of the group
Dragonflies predate dinosaurs by nearly 100 million years - fossils date to 325 million years ago. The largest dragonfly ancestor, Meganeuropsis permiana (285 mya), had a 75cm wingspan, enabled by atmospheric oxygen levels of 31-35% compared to today's 21%. Dragonflies have a 95% hunting success rate - the highest of any predator.
Economic and practical significance of the group
Dragonflies are voracious predators that consume hundreds of mosquitoes daily, providing natural pest control worth millions in reduced mosquito-borne disease risk. A single dragonfly can eat 30 to hundreds of mosquitoes per day.
