Monticello, NY Posts: 488	Hey Guys, I was fishing last evening on the Willow and noticed the usual stuff that been around lately, a mix of caddis, Slate Drake, Sulfurs, etc. but then i started seeing a few quite large Mayflys float past me. I picked one up to get a good look, it was around a size 10, VERY white, wings looked pretty white too, sorry I dont have a pic, maybe I can get one in a day or 2, any thoughts based on time of year and limited description I provided? Im thinking its a Light Cahill of the Species Macaffertium Ithaca Thanks, Adirman

Here are some links: Maccaffertium terminatum - http://www.troutnut.com/hatch/600/Mayfly-Maccaffertium-terminatum Epheron leukon - http://bugguide.net/node/view/316968/bgimage
