Whew! Long list! But very exciting for someone like me who’s trying to collect as much data as possible on these swarms. Thanks to the 300+ participant so far this year. You all make this research possible!

I submitted a report, including mention of swarm for UM/Kansas game.
This website gives a photo of that event re: the dragonflies

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!
