NymphGlossosoma Caddis Larva
The Glossosoma Caddis Larva imitates the saddle-case caddis larvae (Glossosoma species) that are abundant in freestone streams. The pink-tinged Zelon dubbing body matches the natural coloration of these larvae, while the partridge soft hackle legs add movement and realism. A highly effective pattern when trout are feeding on dislodged caddis larvae.

Overview
Glossosoma caddis are among the most abundant caddis species in many western freestone streams. These saddle-case makers build distinctive dome-shaped cases from small pebbles. The larvae have a pinkish cast that this pattern replicates with the Hendrickson pink Zelon dubbing. The amber wire rib adds subtle segmentation and durability.

Fishing Tips
Season
Effective year-round but particularly productive during higher flows when caddis larvae are dislodged from rocks.
Presentation
Dead drift near the bottom where Glossosoma larvae naturally occur. The light weight requires precise depth control.
When to Use
Best when fish are feeding on caddis larvae or as a searching pattern in waters with healthy caddis populations. Excellent during pre-emergence periods.
Water Type
Designed for freestone streams with rocky substrate where Glossosoma caddis thrive. Most effective in riffles and runs.
Rigging Suggestions
Fish as a dropper below a heavier nymph to reach the bottom where caddis larvae live. Works well in tandem rigs.
Visibility & Floatation
Light pattern that sinks slowly. Add split shot if deeper presentations are needed.
