Mayfly Unknown Species - Maccaffertium - Male
Lititz, Lancaster County, Pennsylvania, USA
In a wooded habitat, at a camp called Camp Swatara. Image originally taken in spring 2011, but I am just now submitting it because I have failed to identify it over the years. What mayfly species is this?

Maccaffertium
Hi EmraldYE-

I believe this male imago to be of genus Maccaffertium. Attempting species level identification from the photo of a winged mayfly is best avoided.
