Dry FliesSpent Caddis
The Spent Caddis is a simple yet effective pattern that imitates egg-laying caddis adults resting on the water after depositing their eggs. The dark dun Zelon wings lie flat in a spent position while the olive Zelon dubbing body matches the Brachycentrus and other olive-bodied caddis species. A minimalist design for selective fish.

Overview
The Spent Caddis was developed at Blue Ribbon Flies to match the spent egg-laying caddis that collect on the water during evening hours. The pattern is intentionally sparse to match the delicate appearance of a spent adult. The olive coloration specifically matches the grannom and apple caddis common on western waters.

Fishing Tips
Season
Most effective from June through September during evening caddis activity. Best when female caddis are returning to lay eggs and dying on the water.
Presentation
Dead drift in the surface film with the wings lying flat. Fish slowly and deliberately in the pools and eddies where spent caddis collect. The pattern should sit motionless.
When to Use
Best during the later stages of caddis hatches when egg-laying females are dying on the water. Look for subtle rises and fish taking low-floating insects in the film.
Water Type
Ideal for pools, eddies, and slow-moving sections where spent insects collect. Particularly effective on spring creeks and tailwaters with heavy caddis hatches.
Rigging Suggestions
Fish on 10-12 foot leader with 5X-6X tippet. The sparse design requires delicate presentation. Apply floatant sparingly to maintain low profile.
Visibility & Floatation
Rides low in the surface film like a natural spent caddis. The dark dun wings can be difficult to track in low light. Consider fishing near visible landmarks.
