Just a few swarms to report from the last few weeks:


Tracy, CA



And here is the US map for the last two weeks:

Swarm map 11.8.14 to 11.22.14

Red pins are static swarms, yellow pins are migratory. Click the map to enlarge!

Only 2 swarms in two weeks, but both were migratory, including one international sighting in Spain.  At this point I’ll be surprised if we see any more swarming in the northern hemisphere before the end of the year, but please do report swarms if you see them!  Any northern swarms from here through March will be very exciting.


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!
