Yeah, I agree completely. Truly the tough thing to consider in a photograph is color... back-lighting, dialing up intensity (editing), can change things dramatically.

We can safely agree that the fly pictured is definitely Ephemerella... after that, subvaria (Hendrickson) and invaria (Sulphur) are very close. The wild card here is E. rotunda, which "officially" no longer exists, despite being a full hook size bigger (than invaria) with yellow wing masts and olive highlights in the thorax. Anyway, E. rotunda and E. invaria are now classified as the same insect (E. invaria).

For what it's worth, they continued to be separate to me since they are so physically different. The rotunda's would kick off the "sulphur hatch" in SEPA right around last week in April (give/take a week or two) hatching just after lunch. Invaria's were 2 weeks after and E. dorothea another 2 weeks later (again, rough estimates and variable from year-to-year).

I guess for me the overall yellow appearance pushed me towards sulphurs.

The colors here are very close to the insects, I did edit, but mostly just cropping and sharpening. Like Ard and webrx said I'll just match the hatch whatever it is, thanks for the info guys.

I'm pretty sure that it's a female Hendrickson, but Tim said that he thought the hatch should have been over 2 weeks ago and I wasn't about to argue with him.
it's a very cool picture though.

yellowish green mayfly...thats not of the level of prowess of others here...but I would fish any yellow/olive adult I had tied in my can...I would call it a sulphur...but one of our more astute colleagues said that might not be it due to timimg...but you know maybe it was point man on a scouting mission???

outstanding pics...all around very well shared experience...the bugs are the hardest thing for me to get...hats off...the one handed camera pics are not easy either...I actually lost an old canon that way a few years back...taught me a big lesson...the factory said something like I should get a housing???LOL...

look forward to your next post...ted

Hi bear.
As mentioned The second Pic is a Real Cracker from your results you have a Fly which they liked.
Even though I've caught Brookies they weren't as big as those beauties.
