July started off a little slow, with a few swarms reported in the central part of the country along with a cluster in North Carolina.  For whatever reason, there were several swarms reported in drought-ridden  southern California, an area that normally sees very little swarming activity.  Perhaps these are dragonflies about to move to a better area?  The week of July 12th saw a little more activity in the Midwest, with swarms occurring along the Great Lakes, the Illinois River, and the Mississippi River with a smattering of other swarms across the country.  The week of July 19th saw increased activity along the Illinois and Mississippi, but still little along the western coast of Lake Michigan.  A flurry of activity in that area suggests that the migration season is about to begin, and that flurry started last week, the week of July 26.  That coupled with the sightings along the Mississippi and Missouri Rivers and in Arkansas, Oklahoma, and Louisiana suggest that the 2015 Midwest migration may have already begun!  It’s a few weeks earlier than normal, so it will be interesting to see if the dragonflies continue southward over the next few weeks or stay in place for a little while before they start moving at their regular time in mid-August.  The coastal migrations have apparently not yet begun, though I suspect they may start in the next few weeks.

Peak swarm season has begun!  If you see swarms, I’d love to hear from you.  Click on the link below to add your story!
