Swarm Sunday – 6/17/2012 – 6/23/2012

Looks like the swarm season is starting to heat up!  And there are a few hotspots of activity too.  The following swarms have been reported over the last week:

USA:

Boulder, CO
Denver, CO
Colorado Springs, CO (2 swarms)
Holyoke, CO
Manitou Springs, CO
Bradenton, FL
Chicago, IL
Round Lake, IL (2 swarms)
Lima, OH
Avenel, NJ
Bradley Beach, NJ
Normandy Beach, NJ
North Middletown, NJ
Waretown, NJ
Oak Beach, NY
New York, NY
West Islip, NY

Canada:

Lower Sackville, NS

Clearly most of the early activity is centered over the New Jersey/New York area and Colorado.  Most people from the former have reported flooding in their areas, so that fits nicely with my hypothesis that flooding influences swarm activity.   Interestingly, there is a significant fire in the Manitou Springs area of Colorado, so it makes me wonder if that might be generating swarm activity in the Manitou and Colorado Springs areas.  Not sure I’ll ever be able to test that hypothesis, but it’s an interesting thing to think about at least!  I hope the fire goes out soon though.  I grew up in Colorado Springs and it makes me sad to think that places I loved as a kid are going up in flames…

In other news, I’m planning to move my dragonfly swarm project over to another website in the not-too-distant future.  I think it’s time to lay the project out more formally and have the important information up front and center rather than buried in a series of blog posts.  I’ll let you all know when that happens!  In the meantime, keep sending in your reports here.  Every report helps us all understand this behavior a little better!

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. We get them in Australia but not in swarms – hell!

    • Oh, but you DO get them in swarms in Australia! I don’t get a ton of reports from your part of the world, but I do get some. One of the best videos of a migratory swarm on YouTube is from Australia too! It probably depends a bit on where you’re located, but you definitely get them on both the east and west coasts. Maybe you’ll have a chance to see one!

  2. I haven’t seen a dragonfly swarm yet, but if I do, I’ll send pics!

  3. I feel cheated! I haven’t seen any swarms in Colorado yet.

  4. If you scroll down on this this Facebook page, you will find a photo of a massive Aeshnidae swarm. It’s some sort of Aeshna, but beyond that I have no idea. Calhan, CO. http://www.facebook.com/KRDONewsChannel13

    • I just saw that and posted it to my FB page. Super cool! It’s curious that they aren’t green darners. Most of the swarms from Colorado have reported green darners, so this is a new sort of swarm I haven’t heard about from that area before. Thanks for posting the link so people can see it! This is an impressive swarm, and from a little town I know well and love.
