As per the name this is a caddis imitation and does a great job of this in smaller sizes. However, I like to use this in large sizes as well (think 12 and bigger) as a general terrestrial pattern. It has a great footprint on the water and when the fish are looking for anything and everything floating down stream in the surface it has proven handy. The Dirty Bug Yarn is a great material and proves its versatility with this pattern, I love the mottled coloring on a lot of the options you can get with it.
