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.

Baetidae (Blue-Winged Olive) Mayfly Nymph Pictures

Here's a rather different tiny Baetid nymph. The tails are all unbanded, and the tergites all have a dark-colored anterior 2/3 and light-colored posterior 1/3. The gill veinlets are indistinct. It's probably a very early instar of some Baetis species.

This mayfly was collected from unknown in Wisconsin on January 31st, 2004 and added to Troutnut.com by Troutnut on January 25th, 2006.
