Blue-winged Olives
Baetis
Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

This specimen appears to be of the same species as this one collected in the same spot two months earlier. The identification of both is tentative. This one suffered some physical damage before being photographed, too, so the colors aren't totally natural. I was mostly photographing it to test out some new camera setting idea, which worked really well for a couple of closeups.

I've submitted pictures of these before but Kogotus/Rickera wasn't as far along in it's instars and there weren't any live pictures of Isoperla mormona.
Kogotus/Rickeri can be found here:

The first three pictures are of Kogotus/Rickeri and the last two are of Isoperla mormona.

Wonderful pictures as always, Mark. Beautiful creatures up-close too! Thanks for sharing.

No matter how big the one you just caught is, there's always a bigger one out there somewhere...

Talk to me about the second from last pic...The littler one in the group. Different hatch years? Is this stone on a two year hatch cycle?
I have found Hex nymphs in our Manistee that are like that. One a larger size and another half as big. I assumed that one was slated to hatch the following year (I found them after Labor Day), and the smaller one the years after?

Eric and Jonathan - Thanks for the kind words.
Spence - The latest word I've found has been that no one knows for sure but for Isoperla nymphs it's generally assumed that it's one year. I would guess that the smaller one will transform this year. It may also be a male, they tend to be smaller than the females.
As for the Kogotus/Rickeri no one has checked out it's time for remaining a nymph or at least I'm unable to find anything.
