Why do dragonflies migrate?

Answer 1

Dragon flies swarm due to abundant supply of food in the area. They also swarm to mate. This is less likely because males are more aggressive around other males during mating.

Answer 2

Dragonflies of the same species turn into adults at the same time, so they all emerge from their aquatic stage at once. It only looks like they're swarming. Dragonflies don't have hives or colonies, it's each for themselves.

Answer 3

If you see a swarm of dragonflies, it means they are on the hunt. They will swarm together in order to hunt and catch another group of swarming insects.

Answer 4

Dragonflies don't fly in swarms.

Answer 5

Because they are eating insects
