Tim Flagler of Tightline Productions brings his signature blend of innovation and utility to this adaptable nymph pattern, which he calls the Corded Cased Caddis. It’s a subtle nod to realism with just enough versatility to earn a permanent spot in your fly box.

Although true cased caddis don’t have tails, Tim intentionally adds coq de Leon fibers to make this fly pull double duty. It’s convincing enough to pass as a mayfly nymph too—particularly in faster runs where fish don’t get a long look.

The standout feature here is the corded body technique. This simple twist in application adds segmentation, durability, and texture, and can be applied to a wide variety of other patterns. It also gives the fly a slightly irregular profile that triggers strikes from curious or pressured trout.

Whether you're targeting caddis-eating fish or just need a dependable searching pattern, this one is a workhorse. Tie a few in different sizes, and you’ll be ready for anything from spring creeks to freestone rivers.
