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.

Neoleptophlebia Mayfly Nymph Neoleptophlebia Mayfly Nymph

Dorsal view of a Neoleptophlebia (Leptophlebiidae) Mayfly Nymph from the Yakima River in Washington

Some characteristics from the microscope images for the tentative species id: The postero-lateral projections are found only on segment 9, not segment 8. Based on the key in Jacobus et al. (2014), it appears to key to Neoleptophlebia adoptiva or Neoleptophlebia heteronea, same as this specimen with pretty different abdominal markings. However, distinguishing between those calls for comparing the lengths of the second and third segment of the labial palp, and this one (like the other one) only seems to have two segments. So I'm stuck on them both. It's likely that the fact that they're immature nymphs stymies identification in some important way.

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.
