Cape May in Cape May County, New Jersey — The American Northeast (Mid-Atlantic)
Swarms of Dragonﬂies
—Wildlife Migration —
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?
