Hoping some of you all can help me. I was out bank-fishing at a public park, playing with the Bluegill and other panfish. We my wife and I left, I found a Mayfly inside the vehicle. My wife took a pic of it. I'm hoping someone can tell me what species it is? It's about a size 14. A hatch starting to happen would probably explain why the fish were going nuts for a Heterogenius Nymphs.
