Swarm Sunday – 8/14/11 – 8/20/2011

Another great week of dragonfly swarm reporting!  This past week saw the rise of the “bugnado,” swirling swarms of midges, in various parts of the Midwestern US along the Missouri River.  According to some reports, these bugnadoes are attracting dragonflies that then form swarms themselves.  It’s like an enormous all-you-can-eat buffet for the dragonflies!  However, it sounds like some people in the areas where these bugnadoes are forming are less than thrilled about the arrival of huge numbers of dragonflies, even if they are ridding them of unwanted bugnadoes.  For example, check out the brief report on MyWeatherTech.com.  “To make matters worse?”  Sigh…  I can only wish I were lucky enough to see one of these bugnado-induced dragonfly swarms!

Before I end this post, I’d like to direct everyone to a post that Jim Johnson at Northwest Dragonflier posted this week about the variegated meadowhawk migration in the Pacific Northwest.  He’s got a list of ways you can help scientists (including me!) understand the variegated meadowhawk migration and contribute to a greater understanding of migratory and swarming behaviors.  Citizen Science for the win!    Also, Harlan Ratcliff at The Roused Bear demonstrates how difficult it is to photograph a dragonfly swarm.  Check it out!

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. Edwin, one of my students, first spotted the swarm yesterday, August 22, 2011 in the church parking lot outside our school. We are on Marco Island – 6 miles by 4 miles with over 100 miles of salt water canals south of Naples on the edge of the Big Cypress Preserve and the Everglades. The swarm lasted 2 or 3 hours and attracted a flock of swifts began feeding on the dragonflies and the swarm began to break up. We had an approaching thunder storm just a little later.
