Do dragonflies eat aquatic insects?
Dragonfly nymphs eat aquatic insects, though large ones may also prey on tadpoles and small fish. Adult dragonflies eat other flying insects.
Dragonflies eat other flying insects, particularly midges and mosquitoes. They also will take butterflies, moths and smaller dragonflies. The larvae, which live in water, eat almost any living thing smaller than themselves. Larger dragonfly larvae sometimes eat small fish or fry. Usually they eat bloodworms or other aquatic insect larvae.
