The Olive Shimmer Caddis is a powerhouse nymph pattern that has earned its place as a go-to fly on Utah’s local waters and rivers across Idaho. Designed with both attraction and functionality in mind, this jig-style fly gets down quickly and stays in the strike zone, making it perfect for targeting trout feeding near the bottom.

Key Features

This pattern starts with a silver tungsten bead head, ensuring it sinks fast even in strong currents. The pale olive thread body gives it a natural caddis appearance, while the iridescent perdigon material adds just the right amount of flash to catch a trout’s eye. The CDC collar provides lifelike movement, mimicking the pulsating motion of an emerging caddis.

Why Fish It?

The Olive Shimmer Caddis is versatile and effective year-round, especially during caddis hatches or as an attractor in a two-fly rig. Its jig-style hook reduces snags, making it ideal for fishing pocket water, riffles, and deep runs. Anglers have seen consistent success with this pattern across various waters, from Utah’s Provo River to Idaho’s Snake and Silver Creek.

Pro Tips

• Pair it with a larger attractor pattern or a dry fly for a nymph-dropper setup.

• Vary your drift depth to find where trout are feeding most actively.

If you’re looking for a nymph that combines realism, durability, and effectiveness, the Olive Shimmer Caddis is a must-try. Tie a few or grab some from our shop and experience the difference on your next outing.
