Dragonfly Swarm Project logoHappy Fourth of July weekend to my American readers – and happy weekend to everyone else!  Let’s take a look at the dragonfly swarming activity of the last week, shall we?  Swarms occurred in the following locations:

Well, that’s not something you see everyday!  Look how many reports of US dragonfly swarms came from the west!  There is still a lot of action taking place along the Front Range in Colorado, as there was last week, with nearly all contributors reporting severe weather in the area.  There were also reports in Utah, Arizona, and Idaho, all of which rarely see swarms.  The two lone eastern static swarms took place in states bordering the Atlantic and there was a migratory event along the northern edge of Lake Superior recently as well.  Overall, a very odd week, so I can’t wait to see what happens next week!  Will it be another weird week with a lot of western swarms, or will the normal pattern of mostly eastern swarms reassert itself?

We’re heading into the peak season this week or next, so expect to see a larger list of swarms coming soon!


Have you seen a dragonfly swarm? I am tracking swarms so I can learn more about this interesting behavior.  If you see one, I’d love to hear from you!  Please visit my Report a Dragonfly Swarm page to fill out the official report form.  It only takes a few minutes! Thanks!
