  • Thread: UTC 70 Denier, Black
  • Tail: Antron Yarn, Cream

  • Casing: FINO Skin, Mottled Olive
  • Rib: Tippet, 4x
  • Thorax: Ostrich Herl, Black

This pattern is effective because of it’s realistic qualities. It could easily be messed up with the wrong substitution. There are a few minor swaps that can be made if you’re in a pinch for materials.

Body: Any flashy dubbing of very similar color will work alright in place of the STS Dubbing.

Casing: Thin Skin with a similar color combination can do the job if needed.

Depending on the size and color of the caddis where you’re fishing, you’ll most likely want to have multiple colors ans sizes. Olive, tan, orange, and obviously caddis green are all solid choices. You can also play around with slight color variations on the casing and beads. Don’t get too crazy or carried away with this ultra realistic pattern.

The Net Builder is a caddis pattern everyone should have in their box. It may not be the most popular, but it’s segmentation, colors, and movement make this fly realistic enough to be the real thing! If you have it in multiple sizes and colors it can cover most of your caddis larva needs no matter where you are, or when you’re there. Plus, they’re relatively easy to tie. They should be looking slick, and coming off the vise in no time. What more could you ask for!

This is a versatile pattern when it comes to ways to fish it. The most common would be in a nymph rig. Let the size, weight, and water depth determine if this is the first or last fly in your rig. You can also successfully fish it as a dropper under a dry fly. It could fool some fish that are weary of the dry fly during a caddis hatch.
