LOTS of swarms!  Based on the number of swarms I collected this week, I would have assumed that the dragonflies are on the move, but that wasn’t the case.  Nearly every one of these reports was a static swarm and not a migratory swarm!  I’ll bet they’ll start heading south soon though, so be on the lookouts for some really impressive migratory swarms if you live in the Midwest or along the east coast.

Tomorrow’s post is going to be much shorter than usual as I am away from home and am too busy to write a long post.  But look for Well-Nigh Wordless Wednesday on it’s regular day this week and I’ll get back to your regularly scheduled Monday posts next week!


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!

  1. On Saturday evening approx. 7PM to 8:30PM we noticed a large group of dragonflies swarming over an area of 4 neighborhood yards. The temperature was approx. 78 degrees and very humid. We have seen single dragonflies over the summer season but never in such a swarm. They stayed in a large group and remained over the yards and finally dispersed as quickly as they came. The only water available is a large pool in my next door neighbors yard. This may have been the attraction. The insects were very large and easy to spot although, I am unsure of their color. It was quite a sight to see. The location was in Scranton, Pa.

  2. Saw my first dragon fly swarm today in Cherry Hill NJ… quite a site in the backyard and couldn’t help but cheer them on as they ate anything that took flight smaller than them… Yay get those mosquitos! Which I must say have been terrible this year!

Have something to say?
