This Brachycentrus "Apple Caddis" struggled more than its kin in escaping its pupal skin, enabling me to take an underwater picture of it from directly below.  This is sort of a trout's eye view, but I used the flash for the picture so the transparent shuck appears far brighter than it really is.  In this picture: Caddisfly Species Brachycentrus appalachia (Apple Caddis). From the East Branch of the Delaware River in New York.

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.

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.

These are probably 3rd instar larvae of Dicosmoecus gilvipes. The 4th instar larvae will be the round case made of sand grains.  In this picture: Caddisfly Species Dicosmoecus gilvipes (October Caddis). From the Touchet River in Washington.

These big bucket-like nets on the weeds are home to Hydropsychid caddisflies, as I verified by actually taking one apart to look at its inhabitant.  In this picture: Caddisfly Family Hydropsychidae. From Mystery Creek # 42 in Pennsylvania.

A variety of cased caddisfly larvae, probably mostly Neophylax, have clustered along the backside of a rock in fast water.  There seem to be some Helicopsychidae larvae clustered along the bottom, and a few other taxa are mixed in.  It's interesting that several larvae have especially large stones placed over the front openings of their cases, perhaps to block the case off for pupation.

It does seem to be the wrong time of year for Neophylax to be pupating, but that was the ID given for one of these which I collected and photographed up close.  In this picture: Caddisfly Genus Helicopsyche (Speckled Peters) and Caddisfly Genus Neophylax (Autumn Mottled Sedges). From Cayuta Creek in New York.
