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.

With a bit of help from the microscope, this specimen keys clearly and unsurprisingly to Hydropsyche.

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.

Sometimes our experience on the stream is worth documenting, too. These are my best pictures of fly anglers.

I was up close to this pool watching these two trout when one of them swam in close to me. I froze and waited several minutes for it to move away.

Here I was fighting the largest brown trout I've ever had on the end of my line. I never landed it.

Here my dad's fighting a very nice arctic grayling, and this photo caught it mid-jump at the end of his line. This one eventually shook the hook, but we both caught many more in the same size range.

This colorful brown was my dad's first nice trout on a dry fly. It was also the best of the day, taken with a nice cast after doing some slightly crazy wading through silt and deep water to get into position.

My friend Ian throws a fine cast in a section of river that's open year-round. From the bridge, we spotted a very nice brown nymphing, but neither of us could get it to take.
