Blue-winged Olives
Baetis

Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

Setvena wahkeena (Wahkeena Springfly) Stonefly Nymph Setvena wahkeena (Wahkeena Springfly) Stonefly Nymph

Dorsal view of a Setvena wahkeena (Perlodidae) (Wahkeena Springfly) Stonefly Nymph from Mystery Creek #199 in Washington

As far as I can tell, this species has only previously been reported from one site in Oregon along the Columbia gorge. However, the key characteristics are fairly unmistakable in all except for one minor detail:
— 4 small yellow spots on frons visible in photos
— Narrow occipital spinule row curves forward (but doesn’t quite meet on stem of ecdysial suture, as it's supposed to in this species)
— Short spinules on anterior margin of front legs
— Short rposterior row of blunt spinules on abdominal tergae, rather than elongated spinules dorsally
I caught several of these mature nymphs in the fishless, tiny headwaters of a creek high in the Wenatchee Mountains.

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.

Troutnut is a project started in 2003 by salmonid ecologist Jason "Troutnut" Neuswanger to help anglers and fly tyers unabashedly embrace the entomological side of the sport. Learn more about Troutnut or support the project for an enhanced experience here.

Perfect Sunday outing!

The extent of my experience with wild trout is unfortunately limited (save a trip to Colorado last year), but I have to say that a full day spent catching wild browns brings on a new appreciation for trout. The coloration exhibited by these fish is amazing, and they fight as hard, if not harder, than stocked trout double their size (holdovers included). Anyway, I really just wanted to share a few pictures with you guys. Later!

It worked out that I couldn't attach pictures to the post, because I've been wanting to put together a Flickr page for a while. It's only a start, but here are some of the pictures from the outing I spoke of above. Enjoy.

I think there's a bug in the photo uploading code. I really don't have time to find it right now.

One thing that should work, which Wbranch hinted at, is that you could upload the images elsewhere (like Imageshack or Flickr) and just use the img forum code tag to insert them here. That's not ideal but it might work for you in until I can find the other bug.
