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.

Glossosoma (Little Brown Short-horned Sedge) Caddisfly LarvaGlossosoma (Little Brown Short-horned Sedge) Caddisfly Larva
Dorsal view of a Glossosoma (Glossosomatidae) (Little Brown Short-horned Sedge) Caddisfly Larva from the Yakima River in Washington
I caught this tiny larva without a case, but it seems to key pretty clearly to to Glossosomatidae. From there, the lack of sclerites on the mesonotum points to either Glossosoma or Anagapetus. Although it's difficult to see in a 2D image from the microscope, it's pretty clear in the live 3D view that the pronotum is only excised about 1/3 of its length to accommodate the forecoxa, not 2/3, which points to Glossosoma at Couplet 5 of the Key to Genera of Glossosomatidae Larvae.

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.

I still haven't got my good camera gear set up, but I wanted to get my first Alaskan bug specimen online, so I photographed this one with my point+shoot in the raft.

This is my biggest and certainly best stream-resident rainbow to date, a wild 19-incher pulled from a Class III-IV rapids. It's also the first fish ever to take me into my backing.
Here my dad drops his largest resident rainbow ever, after a spectacular fight. It's a good 18 inches.

This is my first-ever lake trout, caught on a spinner before we stopped to unpack the fly rods near the beginning of a 4-day float trip. I caught another of about the same size soon thereafter. The coloration is incredible compared to other lakers I've seen -- a much more believable cousin to the brook trout.

Caudatella hystrix (Ephemerellidae) Mayfly Nymph from Many streams in Montana
This is a widely distributed species in western Montana but never abundant. Note the length of the middle tail, a key to the identification of this genus.

This is also a very rare mayfly. This specimen was the first ever collected in western Montana. Only 5 specimens have been collected from this large river.

This is the first grizzly bear I've seen. It's in Denali National Park. People with long-range binoculars, plus the view through a couple spotting scopes the park installed at this stop, verified that the little light spot my arrow is pointing to is, in fact, a grizzly bear. This is the closest view I got. From Denali National Park in Alaska
In this "close up" of a grizzly bear laying down on an alpine hillside in Denali National Park, you can almost tell it's a bear. From Denali National Park in Alaska
