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:
http://www.troutnut.com/topic/9110/Kogotus-Rickera

Isoperla mormona can be found here:
http://www.troutnut.com/topic/8606/Isoperla-nymphs

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.
