Natural Habitat

Found near freshwater sources like ponds, lakes, marshes, and slow-moving streams, often ranging far into fields and backyards.

Diet & Feeding

Carnivorous. Adults hunt flying insects like mosquitoes, flies, and moths mid-air. Nymphs (larvae) eat aquatic insects, tadpoles, and small fish.

Behavior Patterns

Highly migratory, traveling long distances over multiple generations. They are strong, agile fliers known for their hovering ability and territorial patrol behavior.
