Mayfly ID?

[AllenOK]

Hoping some of you all can help me. I was out bank-fishing at a public park, playing with the Bluegill and other panfish. We my wife and I left, I found a Mayfly inside the vehicle. My wife took a pic of it. I'm hoping someone can tell me what species it is? It's about a size 14. A hatch starting to happen would probably explain why the fish were going nuts for a Heterogenius Nymphs.

BWO spinner? I'm guessing that because of the shape of the eyes.

Ephemerella invaria (sulpher dun) - some might say a variety of Hendrickson. The wings appear quite clear whereas a blue wing olive would appear more grayish (hence the blue wing reference).

Hendricksons have three tails - that fly has two.

Well you have quite a range of opinions.

I'd say it's definitely a Spinner stage due to the clear wings.

I assume this was still or slow water? If so, that plus the size and two tails makes me think Callibaetis. I usually see the spinners with dark blotches along the leading edge of the wings though.
