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.

27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

Cambaridae--probably Orconectes--your two crayfish could be Cambarus or Procambarus though--need pleopod pictures

Ralph-

I believe what David indicated was that the photos don't have a view of the body part(s) necessary to reliably identify it to genus, let alone species, so he confirmed the family is Cambaridae, and indicated it was probably of genus Orconectes, but could also be genus Cambarus or Procambarus.

As Taxon stated you must have morphological features to identify. However, if you wish to impress your friends you could just call it:

Crayfishus vulgarus or Crayfishus mother@#$%us!

tight lines and stay away from those pinchers

When referring to the pincers...do they indicate the sex of a crayfish? One big claw, and they are males? I vaguely remember something about this, or just a pipe dream?

Sayfu, that applies to hermit crabs, the males have one giant claw and the other is tiny...but as far as I know, not to crayfish.

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

Crayfish are notorious for stealing appendages from each other. Fish and other critters can chomp them off as well. They regenerate fairly fast and mud-bugs can often be found with claws of various sizes.
