These are glossosomatids, Jason.  They are probably Glossosoma nigrior, though it is possible that we are looking at mixed species.  The ones to the right with their aggregate of similar sized grains are classic Glossosoma, while the ones to the left with the large anchor pebbles could possibly be Agapetus.  Regardless, they're all commonly referred to as saddle case makers.  In this picture: Caddisfly Family Glossosomatidae (Saddle-case Makers). From Spring Creek in Wisconsin.

There's a very well-camouflaged Baetisca laurentina mayfly nymph resting on the twig in the bottom left corner of this picture. Can you spot him?  In this picture: Mayfly Species Baetisca laurentina (Armored Mayfly). From the Namekagon River in Wisconsin.

The large caddisfly case (really less than 1/2 inch) is a Brachycentridae larva.  The other cases are actually the protective sheaths of black fly (Simuliidae) pupae.  The two antler-like pieces sticking out of each one are not legs, but antennal sheaths.  In this picture: Caddisfly Family Brachycentridae (Apple Caddis and Grannoms) and True Fly Family Simuliidae (Black Flies). From Spring Creek in Wisconsin.

I lifted a rock in pursuit of a stonefly nymph that had scurried beneath it, and instead I found this Ephemera simulans burrowing mayfly nymph waiting to be photographed.  In this picture: Mayfly Species Ephemera simulans (Brown Drake). From the Namekagon River in Wisconsin.
