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.

Glossosoma (Little Brown Short-horned Sedge) Caddisfly Larva Glossosoma (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 don't know how this slipped by me!!!

Our own Mark "Softhackle" Libertone is now international! Hans Weilenmann has a tying demo of Mark's Lil' Dorothy on his site and mentions him as the originator! By name...

Wow! Way to go Libertone! Will you still speak with us mere plebs here on Troutnut? :)

Mark would just cringe at my bastardized soft hackle that I have been tying lately, and dying to try out. I use my dependable bead at the head, and then place in some micro rubber legs behind the bead the flex floss type that become the caddis pupa horns that hang back, after I dub the body then the soft hackle of a sage grouse that has some beautiful prominent barred hackle.
Fortunately for we fly anglers there are folks like Mark that retain the tradition. Good for Mark, and I always take the time to enjoy Hans Weilenmann.
