Mayfly Swarm
Millions of the aquatic mayfly nymphs have hatched, matured and are now emerging from the river bottom to breed. This happens every year, but this is the first time I have been able to truly capture a photo of the astonishing numbers that are here this time of year. After breaking the surface they will only live for a couple days, but will mate and lay eggs before they die.
Whats really matters is that, in order for this to take place, there has to be clean water with low pollution, otherwise the nymphs wouldn't be able to grow in the river sediment below the surface. This is a true sign of the health of this river, so those of you that still believe the Susquehanna river is dangerously polluted are sadly mistaken, and this photo stands as proof. As hard as it was to be out there amongst the swarm, I am very glad I'm able to show it to you.
I will try to keep posting each day, but I am busier than I know how to handle so bear with me while I try to push through my project list. I appreciate all of you for following this page.
