NymphChimarra Caddis Larva
The Chimarra Caddis Larva imitates the tiny reddish-brown caddis larvae that are a significant source of food for trout throughout the year. This pattern is particularly effective during the early spring when these larvae become more active and are often dislodged from their rock homes.

Overview
This pattern imitates the small, dark caddis larvae of the Chimarra genus, often called little black caddis. It's tied with a black or dark brown thread body, fine wire ribbing for segmentation, and a sparse dubbed thorax. A dark bead or thread head completes the compact silhouette. It's ideal for nymph rigs in spring and early summer when these larvae are most active.

Visibility & Floatation
The Chimarra Caddis Larva is designed to sink and stay near the bottom. The Solarez Bone Dry UV resin shell not only gives the fly a realistic appearance but also adds some weight, helping it sink to the bottom.
