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.

This is a striking caddis larva with an interesting color pattern on the head. Here are some characteristics I was able to see under the microscope, but could not easily expose for a picture:
- The prosternal horn is present.
- The mandible is clearly toothed, not formed into a uniform scraper blade.
- The seems to be only 2 major setae on the ventral edge of the hind femur.
- Chloride epithelia seem to be absent from the dorsal side of any abdominal segments.
Based on these characteristics and the ones more easily visible from the pictures, this seems to be Grammotaulius. The key's description of the case is spot-on: "Case cylindrical, made of longitudinally arranged sedge or similar leaves," as is the description of the markings on the head, "Dorsum of head light brownish yellow with numerous discrete, small, dark spots." The spot pattern on the head is a very good match to figure 19.312 of Merritt R.W., Cummins, K.W., and Berg, M.B. (2019). The species ID is based on Grammotaulius betteni being the only species of this genus known in Washington state.

My buddy and I are southern Appalachian frees toners looking to try Colorado fly fishing. We are looking to come out the second week in August. We float fishing last summer and are looking to do some wade fishing with dry flies. Looking for suggestions on where to go and maybe a guide or guide service that could meet these needs. Thanks in advance for any help....Rog1

Living here in Colo. is truly a blessing with anything from big fast freestone rivers to the little blue lines.
In the area that I live, there is more water than I could fish in a lifetime including lakes. The Rocky Mountain Nat. Park is just one place that a person can emerge himself into and never fish the same stretch of water.
The wade fishing is spectacular in this state!! I'd rather wade than float any day because you can take your time and smell the roses. You can really appreciate the sport and the surroundings better. That's just my opinion.
In the areas where I normally fish, there are a few shops with guide services.
Laughing Grizzly fly shop in Longmont. Call 303-772-9110 Dick Shinton is a great guy and guide for this area.
There is also Saint Peters Fly Shop in Ft Collins. They fish the Cache La Poudre which is my favorite medium size rivers with wonderful scenery. The river is one of the last wild freestone rivers in the state. I suggest you fish it before they dam it up.

The Frying Pan that Leakyboots mentioned is very good and very popular. So is the same with the Blue River. Popular being the key word here. If you want a little more room call Minturn Anglers and request fishing the Eagle River. Here's why, the Eagle is a river with easy access and it's not over fished. In reality, it's over looked. Because everyone goes to the Frying Pan or Blue River. The Eagle fishes great all year long, and it has more quality in trout in size and numbers because of being overlooked. It's every bit as good as our famed Arkansas River, just not as crowded.
But here is a list of some of our popular rivers.
In the Northeast;
Cache La Poudre
Big THompson
RMNP
Central Colorado;
Arkansas
Blue
Eagle
South Platte
Northwestern;
Yampa
Colorado
Frying pan
Roaring Fork
Williams Fork
White
Southeastern;
Conejos
Rio Grande
Southwestern;
Rio Grande
Animas
Gunnison
Taylor
But if it's the streams you like, here's a 15 min. video. We have lots of streams, creeks, mid sized and big rivers.
