Best Brown Fly Patterns

Brindle Chute

A go-to Missoula fly in spring and fall. The mixed dubbing body and dyed grizzly hackle makes this fly incredibly attractive to the fish. Developed on the Bitterroot River, this fly works on the Blackfoot River, Clark Fork River and Rock Creek. The Brindle Chute is also an excellent searching pattern, and we find a lot of people using it instead of the Purple haze when prospecting.

Parachute Hare’s Ear

There is something about Hare’s Ear that catches fish. This fly is just about the perfect color of the March Brown, and is one of our most reliable spring flies. The low floating parachute profile allows the natural buggyness of the Hare’s Ear to get into the surface film, allowing the mixed colors and fur textures to be seen by the trout. This stuff works, which is why it’s been around for at least 500 years!!!!

Parachute Pheasant Tail

Pheasant tail is a fish catching machine, whether its sub surface or floating. The Parachute PT has that lifelike movement in the body that fish can’t resist. The parachute style makes sure the body is in the film, so the trout get a good look at it. This is also a good searching pattern late in the season, and has been effective during the March Brown and Mahogany hatch in Montana.

Carnage Western March Brown

The Carnage March Brown is a great representation of this thick mayfly. The extended body provides a great silhouette to the trout, while the foam helps keep it on the surface. The Carnage Series of flies, designed by Adam Trina, float well and perform better, due to the naturally tapering body.

Umpqua Pheasant Tail Tungsten Jig

The Pheasant tail is a great imitation for the March Brown, and the jig style makes it better. The tungsten gets it to the trout faster, while the inverted hook minimizes snagging on the bottom. If you get excited, treat the CDC with Frogs fanny. It adds a lot of sparkle to a sub-surface fly. The down side? You need to redress about every 3-4 casts to keep the CDC dry and holding air bubbles.
