Large dark "saddlebags" on hindwings distinctive. Could be confused with Carolina or Red Saddlebags in poor light. Flies constantly, often gliding, perches infrequently.
Includes most of North America, absent from upper midwest.
Near ponds, other bodies of water. Widespread in migration.
Spring into fall in temperate areas, all year in subtropics.
Predatory on flying insects
Breeds in fish-free temporary or permanent ponds, ditches. (See account for genus Tramea on oviposition.) Partially migratory--some move north to breed and the next generation flies south. May migrate in swarms.
