Pteronarcys californica

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

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.
