What's with the dragon flies?

Yesterday we had a storm roll through & for whatever reason it's brought about a whole colony of dragon flies!  I mean, they're everywhere.  I was at the store (Target of course) when the storm hit & when I was driving home, new Fred was getting dive bombed from so many dragon flies it sounded like rain!  I drove through at least a good half-mile of them!

When I got home, they were all over the yard too!  So see, they're EVERYWHERE!  Weird.  Anyone know what this means?  Perhaps an early & long-lasting summer??

I got the bullies a toy while at Target yesterday.  Howie seemed to like it very much!
