I came across an article at the beginning of the week that discussed how the monarch migration is happening late this year, possibly because of the strange weather that’s occurred across the US.  The dragonflies seem to be doing the same thing.  In the past two weeks I’ve only gotten a handful of migratory swarm reports, and one of them was a report for an event in 2010.  The dragonflies seem to be staying put for now and it will be interesting to see what happens with the migration this year!  I hope they don’t wait too long and end up running into the winter…


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. UNITED STATES -WV, MD, Rawlings/ McCoole .. Keyser ,New Creek.. Big Swarm is in Keyser/McCoole. They are just feeding on Knats & bugs.. Flying erratic.. Dragon Flies do very well avoiding vehicles.. They were all at higher location than vehicles. Billions in McCoole MD. 21557

    • I’m hoping you’ll come back and look for a response: were the dragonflies flying around in a localized area or were they moving in a single direction together? I ask because it’s about the time of year for the migrations to start, you’re in the migration corridor for several species, and you saw a whole lot of dragonflies. It sounds like a migratory swarm, but I’d like to check. Thanks!
