What is
Fly anglers live for the "hatches" when trout erupt in a feeding frenzy over the mass emergence aquatic insects from the river's surface. In these moments, trout can become so focused on one specific type of prey that they will pursue only a skillful imitation. Anglers who study aquatic insects to meet this challenge find that they're as captivating as the fish themselves. Every species has its own story, its own personality. We cross paths with these characters at the climax of a perennial drama of life and death, and--as with any great drama or sport--every play means so much more when we know the players inside and out. It's not just about catching fish. It's about knowing the stream and loving everything in it.'s aquatic insect encyclopedia is a guide to these players and their stories. Read about the behavior of each species and view thousands of closeup photos, or join the fly fishing forum to meet other devotees of the world's healthiest addiction. You can learn the basics of mayflies, caddisflies, or stoneflies. Or dive into the details of storied species like the Hendrickson hatch and the Hex hatch.

Quick customer service compliment to Korkers

By Troutnut on October 30th, 2019, 3:46 pm
I've been wearing Korkers wading boots for years because I like the interchangeable sole system; I mostly use the soles with aluminum bars on the bottom for traction, but sometimes I switch them out to avoid damaging a boat. On a recent trip, the fabric inside the heel of my Buckskin boots tore (probably due to forcing my foot into a wet boot with too much friction too many times), and the tear made it almost impossible to put the boot on. It's the first time that's happened, and I doubt it'll happen again if I'm a bit more diligent about loosening the laces first. Even though my boots were a few months outside the official 1-year warranty date, I filled out a warranty claim, and they replied immediately offering to send replacements. Those came in the mail a few days later, and all I had to do was destroy the old ones so another claim couldn't be filed on the same boots later. That was one of the most painless warranty experiences I've had in a while. Kudos to Korkers.

Quick stop at Silver Creek between deer hunting

By Troutnut on October 17th, 2019
I spent (Spent: The wing position of many aquatic insects when they fall on the water after mating. The wings of both sides lay flat on the water. The word may be used to describe insects with their wings in that position, as well as the position itself.) ten mid-October days in central Idaho almost-but-not-quite getting shots at mule deer bucks, and at one point I found a free evening (the 17th) to wet a line in the famous Nature Conservancy stretch of scenic Silver Creek. I don't know that I've ever seen so many fish, especially nice fish, in one place. That explains why so many other anglers were also there on a very windy October afternoon.

However, the conditions were tough and my skills weren't quite up to the task. Strong wind ripped relentlessly through the valley, suppressing insect activity as well as making stealthy casting a challenge. Fish occasionally rose to tiny BWOs, but only a handful rose consistently. Trying various techniques, I missed some strikes and caught one small brown.

Pretty float down the Yakima Canyon

By Troutnut on October 6th, 2019
A friend who recently moved to Washington joined me October 6th for a fishing float through a lower part of the Yakima River Canyon. The fish were fairly uncooperative. I lost a mid-sized rainbow on a streamer, but they generally weren't interested in those the rest of the time. Small blue-winged olives were hatching at times throughout the afternoon, and they provided the only real action of the day, but the fish rising to them were mostly small. They were a fun challenge, though, because two of the three spots we found pods of fish rising required very difficult casts. They were rising in shaded back eddies, always on the far side of a long stretch of fast, deep water. It was a great opportunity to practice various trick casts that pile up slack at the end, trying to give my flies 2-second drifts instead of 1-second drifts. It's rewarding when that works just right and draws a strike.

This was also the first real test of my new Flycraft Stealth raft, which had only previously been out for a 1-hour evening trip down part of the Snoqualmie. I'm thrilled with it so far. For a craft small enough to easily carry and load on top of my Jeep by myself, it feels exceptionally stable. The build quality and layout are excellent. It rows like a drift boat, but it's more nimble, and it has a similar ability to instantly drop anchor and fish. I've never had that in a boat before and was giddy about it once I figured out I could anchor in moderate current and fish places I couldn't reach otherwise. I also really enjoyed being able to just drop anchor in the shallows and step out of the boat to wade, without having to pull it up on shore or tie it off. That's such a minor nuisance in most other boats, I never would have guessed I'd take so much pleasure in circumventing it.
