Pteronarcys californica

The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

This specimen appears to be of the same species as this one collected in the same spot two months earlier. The identification of both is tentative. This one suffered some physical damage before being photographed, too, so the colors aren't totally natural. I was mostly photographing it to test out some new camera setting idea, which worked really well for a couple of closeups.
27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

This huge pile of stones was deposited alongside a very small brook trout stream in a huge flood about 9 months before this photo was taken.

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.

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.
