What is Troutnut.com?
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.

Troutnut.com'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 evening trip to the mountains

By Troutnut on October 3rd, 2017
After work last night I drove up to the Taylor River, a tributary of the Middle Fork Snoqualmie. I was just in the mood for the aesthetics of this place, and it didn't disappoint. The largest of the several wild coastal cutthroat I caught was less than 8" long, and most were around 6".

I'm glad I enjoy catching small trout in big places.

Fun float down the Yakima

By Troutnut on October 1st, 2017
I drove out from the gloomy rain of the Seattle area this morning to float the Yakima River in the rain shadow of the Cascades. The weather in the lower Canyon reach (from mile 20 to Red's Fly Shop) was beautiful, although a bit windy for casting.

I floated solo in my packraft, which isn't really a good craft for anchoring and fishing, so the plan was just to use the boat to move between spots to get out and wade. At this water level (1500 CFS at Umtanum, fairly low), there still aren't a lot of great spots for that, at least not compared to the total amount of water fishable from a drift boat. I can see why those are so popular on this river. Still, I found a few decent spots.

Insect activity was quiet. I saw one October Caddis flying around and a handful of other things, but the only numerous insects were Baetids of some sort (I didn't catch any), and they weren't especially thick. They did intersect with one of the better spots I stopped, though, and my first cast with a size 18 parachute BWO hooked a nice rainbow, around 18". I fought it for a few minutes and was beginning to tire it out, just about ready to pull the landing net off my back, when I got a little bit too aggressive against its bulldogging and it bent out the little hook and got away. I fished a cast's length downstream for half an hour or so, then tried that spot again, and to amazement I hooked a fish of the same size, in the same spot, on the same fly. It's possible there was more than one nice fish right there, but I'm more inclined to guess this was the same fish hitting again. I've never had a big trout give me a second chance so quickly. I've done it with naive little grayling in Alaska, but this was a first, if indeed that's what happened.

After that, surface activity really died down for the rest of the day. 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.) some time swinging a small olive Sculpzilla, on which I missed too many strikes throughout the day. Some might have been small trout that only nipped the tail, but a couple fish were solidly on the line for a few seconds before dropping it. I think my ten years throwing dry flies to grayling dulled my other technique a bit. Finally I managed a solid hookup in a deep riffle and won a great fight with a 20" rainbow that kept dodging the net, trying to run between my feet, and other crafty tricks.

Mule deer, quail, and other wildlife complemented the golden canyon scenery to make this trip really enjoyable, even though the fishing was slow at times.

Finally got an October Caddis

By Troutnut on September 29th, 2017
I've been itching to photograph one of these for years and had an unexpected opportunity tonight when this one flew into a house full of aquatic scientists. It's the first insect I've collected for this site by chasing it around a kitchen with a tupperware container.

Tonight, this one flew into the kitchen during a pizza party at a house along the river, and was quickly pointed out -- one of the perks of hanging out with other aquatic biologists! Maybe next year I can finally get a salmonfly on taco night or something.

Chasing Golden Trout high in the Cascades

By Troutnut on September 3rd, 2017
I just posted a report on my Labor Day weekend fishing adventure, trying to add a Golden Trout to my life list. Physically, this was the hardest thing I've ever done by far, and it was the only adventure that's ever left me committed to never doing anything remotely like it ever again. But I did encounter some interesting fish -- read the Golden Trout trip report to see how that went.
