Fly fishing some of our many reservoirs in Colorado this June? Don’t leave home without some chironomid patterns in your fly box.
Mature chironomid pupa will hang vertically in the water about 6" off bottom without motion. Every minute or so, they will wiggle and then rest. Brian Chan, a well-known Canadian entomologist, says that “the pupae swirl around in the water one to two feet off the bottom of the lake bed. During this process, they mature (for three to five days before they make their journey to the surface to hatch as adults.”
This explains why the first one to two feet off the lake bottom is often so productive, and also why trout often take chironomid pupa imitations deep in the lake when there is no evidence of a hatch on the surface.
Kenny Romero, Angler’s Covey guide, explains that chironomids wiggle, squirm, and jerk their way to the top in a very slow ascent. Romero suggests “I usually start fishing the chironomid just off the bottom and very slowly strip up with frequent rest stops. This mimics the real deal. When I get a strike, I generally stay in that area until the bite stops. Then go back to prospecting.”
Fishing the chironomid
Two key things to remember:
1) The chironomid emerges from the bottom of the lake so determine the depth and then adjust your strike indicator accordingly to move the fly 10” to 24” from the bottom. After you cast wait a good minute to allow the fly to sink before you begin your retrieve.
2) After the fly has sunk, make your strips and then pause. Get enough movement so your strike indicator makes a wake on the surface.
For June, Angler’s Covey guides like these chironomid patterns:
Jon Kleis and Jon Easdon go to the Jumbo Juju in a size 18
Justin Brenner likes Chan’s Chironomid bomber in different colors

Kenny Romero recommends a variety of red, black, brown and green color chironomids with varying colors of ribbing (gold, white, silver and black) in sizes 18 to 10. When he ties them up, he uses “sparkle yarn or white, for the gills. Often times a simple bead ( white, black, metal, etc. is sufficient). “
I use various curved and straight nymph hooks . I find that a slender body works best. The latest epoxy style chironomids with translucent finish works well. But I also have days where a thicker body thread pattern is the ticket.
