Adult Caddis – Quick Guide
Why the Adult Caddis matters:
-
Surface Action: Unlike mayflies, caddis "skate" and "skitter" on the surface, creating a V-shaped wake that triggers aggressive rises.
-
Key Moments: Most effective during a hatch or when females return to the water to lay eggs.
-
The Strike: Because the insect moves fast, fish often attack with explosive force.
J:son Caddis Adult 4 Brown (#20)
Micro Precision for Selective Fish The J:son Caddis Adult 4 Brown is a micro-imitation with a 13 mm profile on a size #20 hook. It is the ultimate tool for technical waters and wary fish.
Why this fly works:
-
Natural Silhouette: The dark brown color mimics common small caddis species, providing a lifelike profile fish trust.
-
Unsinkable: Features J:son’s signature air-filled wings and foam body. It stays high in the surface film even in ripples.
-
Active Fishing: Its buoyancy allows you to "skate" or twitch the fly to mimic a living insect without it drowning.
-
Stealth Mode: The #20 size is essential for crystal clear water and highly selective trout or grayling.
Pro Tip: This brown version is a "must-have" for evening hatches when silhouettes become more important than fine color details.
