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.

Male Cinygmula par Mayfly Spinner Pictures

This spinner came from one of those huge swarms that make one just stop fishing and admire the spectacle. Not bad for a little-known species.

In the same swarm I collected a female and another male.

Unfortunately these spinners were really fragile and it was hard to get one completely intact. This one's missing some legs.
