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 Cinnamon Brown (#20)
The Micro Hatch-Matcher The J:son Caddis Adult 4 Cinnamon Brown is a micro-imitation featuring a 13 mm profile on a size #20 hook. This "Cinnamon" tone is one of the most effective colors for imitating the most common small caddis species worldwide.
Why this fly works:
-
Natural Triggers: The warm reddish-brown color provides a realistic organic look that fish recognize as a primary food source.
-
Superior Buoyancy: Built with J:son’s signature air-filled wings and a flexible foam body, ensuring it stays dry and visible even in faster water.
-
Lifelike Movement: The high-floating design allows you to twitch and skitter the fly to mimic the "racing" motion of a living insect without it sinking.
-
Technical Stealth: The #20 size is your secret weapon for crystal-clear rivers or glassy lakes where fish are easily spooked.
Pro Tip: Use the Cinnamon Brown version during the peak of summer. It is a fantastic "all-round" color that works in almost any light condition.
