Dry FliesBlack X Caddis
The Black X Caddis is a dark variation of the classic X Caddis pattern designed to imitate black caddis species, particularly Glossosoma (saddle-case makers). Its sparse deer hair wing and slim Zelon dubbing body create a low-riding profile that fish find irresistible during dark caddis emergences. The pattern is simple to tie yet highly effective.

Overview
The Black X Caddis follows the X Caddis design pioneered by Craig Mathews, featuring a trailing shuck and sparse deer hair wing. The black coloration specifically matches Glossosoma caddis that are abundant on many western rivers. This pattern is particularly effective when black caddis are emerging and fish become selective to color.
Pattern Characteristics
Materials
Hook: Tiemco 100 or Umpqua U001, #20
Thread: Uni-Thread, 8/0, black
Shuck: Crinkled Zelon, caddis amber or gold
Body: Zelon Dubbing, glossosoma adult black (or black Antron Dubbing)
Wing: Elk or deer hair, natural micro caddis or X Caddis
Fishing Tips
Season
Most effective from June through September during black caddis emergences. Peak activity occurs in late afternoon and evening hours when adult caddis are most active.
Presentation
Cast upstream and drift drag-free through rising fish. The pattern should ride in the film with the shuck trailing below. A slight twitch at the end of the drift can trigger strikes.
When to Use
Best during black caddis hatches, particularly Glossosoma species. Try when fish are refusing larger, bushier caddis patterns and appear to be taking emergers.
Water Type
Ideal for riffles, runs, and pocket water where caddis emergences occur. Particularly effective on freestone streams with healthy Glossosoma populations.
Rigging Suggestions
Fish on 9-12 foot leader with 5X-6X tippet. The sparse design floats well but may need periodic drying. Apply floatant sparingly to maintain low profile.
Visibility & Floatation
Rides low in the surface film like a natural emerger. The dark coloration can be difficult to track in low light, so consider fishing where you can see the rise rather than the fly.
