Can anyone ID this fly?

[HeavyWater]

Hi. Please let me know if you can ID this fly. If I can upload the photo.

This is another angle of the mayfly.

March Brown/Grey Fox male. I suppose it could also be a Light Cahill which us very similar.

Thanks.

Yeah, I'd vote Light Cahill too.

Maccaffertium for sure, but it doesn't seem light enough for a Cahill. I'd go with the Gray Fox color phase of the March Brown.

Plus, the eyes on a Cahill are much lighter in color.

The large eyes have it, as Redietz says. Gray fox changing into spinner.

 

[HeavyWater]

Thanks again.

Are the large eyes unique to a Grey Fox?

Male mayflies have larger eyes than the females. This isn't unique to march browns.
