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.

The last trout I caught was right before our "christmas snow storm" the month of January was bitterly cold and the snow was deep. Finally on 2/6 the temps got up into the 60's so I had to venture out. I was not the only one with the "itch" there were more anglers than I expected on the water. With the snow melt it clouded the river pretty good adding to the degree of dificulty in hooking into the still winter lying trout. I did not even get a bite at my tiny midge patterns but the goal was to get out and wade. South Platte conditions are improving though we are not out of the woods yet. It is getting close to spring. Midges were coming off pretty well for early Febuary I showed up a little late on the river and I more than likley missed the "window". This is the first year I have not laid down my rod in November and not picked it up until March, my goal was to get out and try my hand at the challenging winter conditions and Ii acheivved my goal. I did not want to loose the "feeling". I also needed to bond with my new RL Winston 9' 4wt. I purchased early December :) Spring is almost here and I can't wait to share the pictures and stories with all of you.

I'm in the same boat - this is the first winter I have kept fishing - last time out (and my last fish) was in late January, with temps in the low 30's - I'm in the northeast, so we're in a deep freeze right now and I haven't been able to get the nerve up to try it when the temperatures struggle to hit the 20's :) But you're right - even if you don't catch anything (so far i've been averaging only 1 fish a trip in the winter) you get your "fix" in and keep the cabin fever at bay.

Due to my aversion to crowds, I'm actually not a big fan of spring fly fishing though - springtime brings a flood of spin fisherman into my back yard. What is in the summer, fall, and winter a peaceful getaway to "connect" with the stream becomes anything BUT relaxing.

No sir - with the arrival of the stocked trout season march 31st, I will begin fishing for stripers from the beach through May while I hide from the crowds. Mid May is usually when I return to the stream....
