Dirty Bug Yarn Caddis

Dirty Bug Yarn Caddis

Tied by South of North Fly Fishing: https://www.youtube.com/@southofnorthflyfishing

As the name suggests, this pattern is built around Dirty Bug Yarn and imitates a caddis, especially well in smaller sizes. But it’s far more than just a caddis fly. In larger sizesβ€”think size 12 and upβ€”it functions beautifully as a general attractor or terrestrial pattern.

Tied by South of North Fly Fishing, this buggy dry sits with an excellent footprint on the water. That means it gets noticed, especially during those β€œanything goes” feeding windows when trout are opportunistic and scanning for movement. The mottled color options available in Dirty Bug Yarn give this fly a natural, variegated look that mimics the irregular texture and tone of real insects.

Whether you're casting into fast runs or slick glides, this pattern has the kind of bugginess that triggers takes. Its simplicity also makes it a fun and fast tie, so you can crank out a few in multiple colors and sizes to cover a range of situations.
