Mayfly ID?

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.

Callibaetis...

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).

Hendrickson dun

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.

Looks like a hexagenia, what we call a willow fly here in the south.

Yes, this was still water. It's way to early for a Hex; plus Hexes are about 3 times bigger.

Honestly, I think species ID probably isn't that important? Just tie up some kind dry fly (probably a parachute; I'm fairly good at those) with white tail, a dark abdomen, and appropriate colors elsewhere, on a size 14 hook.

One more time:

The speckle winged Callibaetis genus contains on average the largest species in the Baetidae family with hatches ranging in size from 20 to 12 (6mm to 12mm). However, most can be matched with 14 and 16 imitations. They reside only in very slow weedy sections of rivers or lakes and ponds.

This is a Callibaetis spinner from Trumbull lake, at 9700' in the Eastern Sierras. They have two broods that hatch each Summer - the first one is #14 and the next #16, In some locations, there will be three hatches during the summer # 14 - #18:

The Quigley Last Chance Cripple is a good imitation for this bug (cut & paste,scroll down) :
