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

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.
