Tim Flagler of Tightline Productions demonstrates how to tie Pat Dorsey’s Mercury Midge in this fly tying video tutorial.

Make’em Eat Midge Patterns

Popular in the Rocky Mountains of Colorado, this fly flat out produces fish when no other will in areas like Cheesman Canyon, Deckers and the Dream Stream. One of Pat Dorsey’s trade secrets, the Mercury Midge is a go-to fly when the fish decide they are not going to eat.

What really makes this midge pattern tick is the Killer Caddis glass bead that really does look like a small gas bubble under water. This simulates the gas bubble generated during midge pupation that provides the midge a lift to the water surface.
