Spring creek hatch id?

[discomidge]

Hey, just got back from a real nice day on spring creek and am hoping someone might be able to tell me what I saw hatching all afternoon. There were plenty of BWOs and midges flying around, but there were also two different and much larger mayflies. I only managed to snag one of them which was about a 16, had a light green abdomen, darker slightly rusty orange thorax, blue gray wings and two long white tail things. Fish werent really paying attention to them, but I was surprised to see bigger mayflies hatching in decent numbers.

The other big bug was larger, maybe a 14, and in the air it looked like it had a fuller, bushier tail and was maybe slightly reddish. But that’s all just a guess cuz I never got one, despite my wild hat swinging.

Thanks!
