Hey guys…I found this mayfly this afternoon at home. Do you have something similar up there? What do you think it is exactly? Scientific name? Can fit on a #14 or 16 hook:D
Thank you in advance.

My first impression is to go with a “Brown No-hackle” ~
(hope this copies)
Hey Dale, my question was about the bug, not with which fly to imitate it (an Adams seems to be perfect)
Thanks anyway,
RF
Sorry … I misunderstood.
In these parts I’d call that a mayfly dun.
Looks like a March Brown to me. The duns have two tails, unlike most other mayflies.
The scientific name, if I am correct (hard to be sure without measuring and knowing emergence), it might be the Maccaffertium Vicarium.
The insect would be approx. 14-16mm in size.
Have to agree with Byron, looks like a March Brown. They look like large sailboats when floating down the river mixed in with the Blue Wing Olives.

Looks a lot like a Quill Gordon (Epeorus pleuralis) to me. The Adams would be a good imitation.
Hard to tell and a #16 would be too small for the Gordon. It’s normally a #12.

My guess is some type of the Maccaffertium.
Wing mottling and number of tails would be wrong for Epeorus.
Isn’t it mid-fall in Argentina? Are there any flies here outside of the various small types of BWO’s that hatch in the fall?
Really? I’m no math whiz but I can count to two.
Not saying for sure it’s a Quill Gordon, just very similar.
You’re right. I’m an idiot.
I now you did not solicit a pattern, but I think one of these might do?

Steven…thanks. And I don’t know, I mean I am m not in Patagonia at this time (trout region) but near Buenos Aires. So I’m not fishing; the mayfly appeared at home. I also checked March Browns in this area. Bigger and darker than this relatively pale mayfly. Yes, it’s beginning of fall.
However, I think it is very interesting to compare the bugs (in this case a mayfly) that you have in the North America with our insects and see (if any) the differences.
This one is very usual in Patagonian lakes
.
I have a few books with pictures of bugs, but I alway check Troutnut.com when these questions appear online.

Could also be a female Calibaetis:
The fly in post 12 has very obvious hind wings.
It was from a lake and the calibaetis like lakes. Although less pronounced from one picture, the Calibaetis does have hind wings.
Believe me, if the answer on Jeopardy was “this may fly has speckled wings and lives in lakes,” my answer would be “What is a Callibaetis?”
But the Callibaetis has minute hind wings as in your picture, not large obvious hind wings as in Rocketfish’s picture. Also, burrowing may flies live in lakes as well (Mackinac Island on Michigan’s UP is covered in Hex and Brown Drakes in July from the hatches on Lake Michigan).
Rocketfish’s pictures might be of genera we don’t have here. That said, I’d go with a classic March Brown but substitute teal for the wing.
Steven,
I was just trying to help identify the bug for the guy. My first guess was a March Brown. Then, he posted the second pic. Which mentioned a lake as the source…another clue.
So, we had: 2 tails, somewhat speckled, and perhaps from a lake (slow water).
If it is from Argentina, it may not correspond directly to the insects here. So, perhaps it might be in the family…
In addition, the first pic. Posted did not appear, to me, to have a large hind wing…
I think those are two different bugs.
Yes Steven, are two different bugs as I pointed.
My question was about the first one. It seems some pale mayfly, very different to the second one which is a Patagonian mayfly, 1,000 miles (South) from the first one.
So my main doubt was if you have the same (first) mayfly in US and in that case, what is it (scientifically) in your records.
Good luck.
