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!

    • Thanks! I saw the website you linked to earlier today and I’m hoping someone will have better photos of the dragonflies in the swarm so I can identify the species that was involved. Looks like they were wandering gliders, which would make sense if it happened right before a storm as that species is known to be associated with storms. Wish I could have seen it!

Have something to say?
