A Brachycentrus "Apple Caddis" pupa scoots around in the surface film.  Apparently it had some difficulty emerging, so I was able to slip my camera underneath it and take a picture from below.  In this picture: Caddisfly Species Brachycentrus appalachia (Apple Caddis). From the East Branch of the Delaware River in New York.

A crayfish chews on a Hexagenia limbata nymph shortly after a small Hex emergence.  I didn't catch any fish, but playing around with my flashlight and camera in the rocks proved productive.  In this picture: Arthropod Order Decapoda (Crayfish) and Mayfly Species Hexagenia limbata (Hex). From the Namekagon River in Wisconsin.

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.

Here's the surface of the river viewed from below during a Tricorythodes spinner fall.  Several dead spinners are visible.  In this picture: Mayfly Genus Tricorythodes (Tricos). From the Namekagon River in Wisconsin.

I tried to photograph this salamander but it kept scurrying away from the camera.  The rocks in this little backwater are covered with a thin layer of very easily disturbed silt, so anywhere I followed it I didn't have much time to photograph before the water was too turbid for a good shot.  This is the best I got.  In this picture: Amphibian Order Caudata (Salamanders). From the East Branch of Trout Brook in New York.
