Status
Swamp Darner (Epiaeschna heros) is the largest dragonfly species in Maryland, and one of the largest in the east. As the name suggests, this species breeds in wooded swamps, where females oviposit into rotting wood. This species can often be seen on summer evenings hunting over forested areas in impressive feeding swarms (Paulson, 2011). Swamp Darners are common in Maryland, and there are records from every county (Richard Orr's The Dragonflies and Damselflies of Maryland and the District of Columbia).
Description
The elongate ringed abdomen, dark-and-green coloration, blue eyes, and large size of Swamp Darner are distinctive. Cyrano Darner (Nasiaeschna pentacantha) is similar in color, and often occurs in the same habitat.

Epiaeschna heros, the swamp darner, is a species of darner in the dragonfly family Aeshnidae. It is found in eastern North America.[2][3][1][4] It is the only extant member of the genus Epiaeschna, a genus that is well-represented in fossil specimens found in Eurasia, suggesting a wider distribution during the mid-Cenozoic.[5]
The IUCN conservation status of Epiaeschna heros is "LC", least concern, with no immediate threat to the species' survival. The population is stable. The IUCN status was reviewed in 2017.[1][6][7]
The species has been witnessed feeding on Solenopsis invicta ants during nuptial flights.[8]
