What is the biggest mayfly species in the North East? I was at a 7 to 8 acre pond tonight that holds some nice trout, and I swear I saw some spinners about size 8 or 6! I had to do a double-take to make sure it was a mayfly! I didnt have my camera, so no pictures but Ill try and get some soon. It looked dark brown and around 2, possibly 3 inches in length.

Ok, so I originally thought it was Hex, but I didn't think they were that big. After looking at the pictures on here, I'm sure it was a Hex.

There are only three mayfly genera with really large mayflies, which I would describe as being in excess of 1" in length, as measured from the front of head to end of abdomen, exclusive of tails.

These are Ephemera, Hexagenia, and Litobrancha, all burrowers in family Ephemeridae. Of those three genera, only Hexagenia are found in ponds.

At this time of year, it was probably a different species of Hex, like Hexagenia atrocaudata. Check out the pics of that one on this site and see if they match a little closer still.
