Costa Rica:


With the exception of the recent swarm boom in Colorado, the western US hasn’t seen a lot of dragonfly activity so far this year.  That changed this week with reports cropping up in Utah, South Dakota, Arizona, and California.  There’s not a whole lot of activity there, but it’s a pretty good showing for the west where swarms are far and few between.  Otherwise, things seem to be continuing along as they have been, with activity centered over New Jersey/New York/Pennsylvania and spread throughout the southeast.  The eastern part of the country seems oddly consistent this year.  Interesting!

I got to see another swarm this week too!  It was the exact sort of swarm I’ve heard about so many times from people who have participated in my project too: green darners flying just overhead as it became dark and just before a huge storm blew into the area.  Having spent so much time working on this project in the west where swarm sightings are incredibly rare, it’s great to see firsthand a swarm like the ones I’ve been hearing about for the past three years!  Considering I’ve seen two swarms in two weeks, I am hopeful I will get to see several more swarms before the season is over.

It’s been a great year for dragonfly swarms so far, and the peak of the season hasn’t even begun.  I think this is going to be the best year yet!

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!
