Swarms of Dragonflies
Dragonfly Migration
On one recent September day, over 400,000 dragonflies swarmed Cape May. Migrating dragonflies may form swarms between late July and the middle of October, and most often during September.
These harmless insects become more concentrated at peninsulas and other coastal locations after cold fronts. Most dragonfly migration swarms follow geographical features in the landscape, such as coastlines, lake shores, and even the Garden State Parkway.
There is still much to learn about their migration. Researchers are trying to determine their origin, their destination, and the distance that they travel. Fat deposits in the abdomens suggest they may migrate long distances. Where do you think they are going?
