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.

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: True Fly Family Simuliidae (Black Flies) and Caddisfly Family Brachycentridae (Apple Caddis and Grannoms). From Spring Creek in Wisconsin.
