How strange that there have been so few swarms this week!  I’ve heard reports from several people along the east coast of weather that changed from very warm to cool literally overnight, just like what happened where I live.  Last Saturday we had a huge storm and Sunday was a good 20 degrees cooler.  Perhaps the cold front is impacting the dragonfly flight?  I really have no idea what’s going on at this point.  It’s very odd to have so few swarms in the middle of the normal peak season.

About half of the swarms reported this week were migratory swarms, however.  The migration seems to be ongoing in the Midwest and along the west coast as most of the swarms reported from both regions were migratory.  But in the east…  Still nothing!  There were two reports in the same area of Florida of a massive migratory swarm, but where did it come from?  No one reported any movement in the east all week and then a giant swarm appeared out of nowhere in Florida.  Curiouser and curiouser!  Normally I get 20 reports of a single big swarm moving down the coast in 4 or 5 different states, but no one saw this one before it hit Florida.  Did it originate in Florida?  Or did all those people simply miss this one?

Honestly, though, getting unexpected results can be more exciting than confirming what you already know.  Now I’ve got this big mystery, an odd thing that I can’t explain.  Perhaps this coming week will provide some answers, so keep those reports coming!
