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.

Caddisfly Genus Protoptila (Saddle-case Makers)

These very tiny caddisflies (hook size 24-28) are not very important to anglers, because of both their size and the fact that they prefer warmer water. On rare occasions they are abundant enough to be significant.

None of the books I've checked suggest which individual species are important.
