Salmonflies
Pteronarcys californica

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

I spent more than an hour casting to several rising trout in this pool and caught only two. Its clear water and tricky currents harbor dozens of free-rising, usually very hard-to-catch fish.

This seems to be a young larva of Limnephilus. Although not clear in the picture, several ventral abdominal segments have chloride epithelia.

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.

Female Attenella attenuata (Small Eastern Blue-Winged Olive) Mayfly Dun Pictures

This dun was badly damaged in transport and all its legs fell off, but I photographed it anyway because I wasn't sure I would fine more and it's an interesting species. Luckily I collected better specimens a few days later.
