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.
