Saw these for the first time when we were in Ft.Myers beach in March. They were everywhere for about 2-3 hours and then all of a sudden they were gone. Not really a bug person, but I am sure I am not alone. These particular little bugs are just plain annoying. I didn't even want to talk for fear of them flying in my mouth. After being there for several days then we headed up to Disney, and we saw none, thank goodness. But after reading several of the posts on here it seems that they start further south and make their way up state???
