Lots of activity reported from the northeastern US, including the areas around the upper Midwest and New England.  Starting to look a lot more like the migration season is upon us!  Next week I expect to start seeing increased reporting in the mid-Atlantic states and perhaps a few more in Nebraska, Arkansas, and Missouri.

This is the prime season for swarms, so be on the lookout in your area!  If you’re along the east coast or any of the rivers in the Midwest, you’re likely to see swarms over the next few weeks.  Hope you’ll report any you see!

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!
