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 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.

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.

A peculiar mayfly nymph clings to a log. I'm not sure if it's a Heptageniid clinger or a flat-bodied Ephemerellid crawler, but I don't believe it's a species I've collected yet. In this picture: Insect Order Ephemeroptera (Mayflies). From Eighteenmile Creek in Wisconsin.
