Hex Mayflies
Hexagenia limbata
The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.

This specimen keys pretty easily to Onocosmoecus, and it closely resembles a specimen from Alaska which caddis expert Dave Ruiter recognized as this genus. As with that specimen, the only species in the genus documented in this area is Onocosmoecus unicolor, but Dave suggested for that specimen that there might be multiple not-yet-distinguished species under the unicolor umbrella and it would be best to stick with the genus-level ID. I'm doing the same for this one.

Hi,
My son and I just returned from a trip to the Chillean side of Patagonia.
Other than Caddis, beetles, and hoppers, there was not a lot of insect activity.
I did see this spinner and believe I know what it is, but looking for verification.

Byron,
I'll bite, a member of Leptophlebiidae. You seem to have lost two of the caudal tails (or possibly just one if I'm entirely wrong). Can't even begin to guess the genera if I'm right, there are just too many.

Based on the long legs, body shape and heavy wing venation I'll go with heptageniid... Only a guess, though.

Kurt-
That was my instinct as well, at least until I discovered that South America doesn't have a single species of family Hetageniidae. You will have to copy and paste
http://www.flyfishingentomology.com/SAMayflyDistributionQuery.htm
into your web brouser's address window in order verify that, as this forum converts all hyperlinked addresses to all lower case for some unknown reason.
Hint hint, Jason :-)

Kurt and Roger,
Or perhaps a member of Nesameletidae. Found this picture of a female.

It's a New Zealand site but the genus shows up in Chile as well.
