Hexagenia Limbata

Mayflies have been hatching in central Wisconsin. There were easily thousands in this video, but you'll have to look closely to see them in the air...there's no zoom on my GoPros. These are hex, the biggest we have locally. Brown drakes are over, pretty sure sulfurs are as well. The hex are going strong on many rivers right meow, and it won't be too long before the whites show up in certain areas.
