Walk into any fly shop in Colorado and you'll see walls covered in chironomid patterns — dozens of variations in every color imaginable. It's overwhelming, and most of it is unnecessary. After years of guiding and fishing Colorado's best stillwaters, I've narrowed it down to 5 patterns that cover 95% of situations you'll encounter at Antero, Spinney Mountain, 11 Mile, and Delaney Buttes.
The most versatile chironomid in Colorado. A tungsten bead, brown body with gold ribbing, and subtle flash triggers fish across every water we fish. When in doubt, tie on a Chocolate Gold. It works in 6 feet and 20 feet, in clear water and stained water, in spring and fall. This is the pattern I reach for first on any new water.
Black thread, red wire, white bead. This classic combination has been producing fish on Colorado's stillwaters for decades. The high-contrast silhouette is visible in low light and stained water, and the white bead creates a hotspot that trout target. Particularly deadly during early morning and late evening sessions when light levels are low.
Discovered by the legendary Musky John, this pattern features a realistic wing case that perfectly imitates the emerging profile of a chironomid pupa. On pressured water like Antero on a busy weekend, this level of detail matters. The wing case creates a subtle silhouette difference that finicky fish respond to when they're ignoring everything else.
The ultimate searching pattern. When you arrive at a new water and don't know what depth, what color, or what size the fish are keying on, tie on a Chirono'midge' and start working through depths methodically. The tungsten bead gets it down fast and the slim profile matches the majority of Colorado's chironomid species at their natural size.
When the standard patterns stop producing, the Burnt Wino often turns things around. Inspired by the legendary Wino pattern and adapted by tier Kyle Glass, the deep amber and copper tones of this fly match the darker, more mature chironomid pupae that predominate in the fall. An essential pattern for September and October fishing on any Colorado stillwater.
The other half is depth and presentation. The fly box on top of every guide's net is full of these five patterns — but the anglers consistently outfishing the bank crew aren't doing it because of the fly. They're doing it because they've solved chironomid depth control and they've dialed in a clean indicator rig. If you're new to stillwater, start with our chironomid primer. If you're heading to Antero specifically, the Antero seasonal pattern breakdown covers which of these five to lead with month by month. And if you've fished chironomids for a while but the numbers haven't grown, read the #1 mistake stillwater anglers make — odds are it's costing you fish.
All five of these patterns are available through Trout Tricks in 5-packs. They're tied on 2x heavy wire hooks so they handle Colorado's big trout without bending out, and the tungsten beads get them to the strike zone fast. Shop the full selection and use them on your next stillwater trip.
