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.

Dorsal view of a Pycnopsyche guttifera (Limnephilidae) (Great Autumn Brown Sedge) Caddisfly Larva from the Yakima River in Washington

This specimen appears to be of the same species as this one collected in the same spot two months earlier. The identification of both is tentative. This one suffered some physical damage before being photographed, too, so the colors aren't totally natural. I was mostly photographing it to test out some new camera setting idea, which worked really well for a couple of closeups.

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.

A couple hours on the Middle Fork Snoqualmie

By Troutnut on August 3rd, 2019

I talked my wife into a quick trip to one of our home rivers on August 4th. It was the lowest I've ever fished it (around 235 CFS downstream at the gage, far less up by us), and that made for some easy wading. Some of the pools were practically still-water fishing. However, we hit a particularly good one at dusk where we caught dozens of fish without even having to move our feet. The big ones of the night were 7-8", but it's still fun.

For a species not yet reported in my state, I've been surprised to find these in two different locations lately. I was tempted to think they're the more common Paraleptophlebia debilis, but the characteristic big dorsal bump on the claspers just isn't present.
