Master the Surface Action
Adult caddis flies are a cornerstone of fly fishing, found in both still and moving water across the globe. They are most commonly seen on the surface during two critical moments: when they first hatch and when the females return to lay their eggs.
Unlike mayflies that often float passively, adult caddis are known for their frantic movement. When hatching or depositing eggs, they skitter across the water with impressive speed, creating a V-shaped wake that looks like a small racing boat. This "skating" motion often triggers explosive, aggressive rises from trout and grayling. While a newly hatched caddis is a tempting target, an egg-laying female—often carrying a visible egg sac—is a high-protein prize that large fish will move great distances to intercept.
How to fish the J:son Adult Caddis:
-
Dead Drift: Cast upstream and let the fly float naturally over rising fish.
-
The "Skating" Technique: Cast across or slightly downstream and use the rod tip to make the fly twitch or "skitter" across the surface to trigger an attack.
-
The Lift: Just before the end of the drift, let the current tension lift the fly off the water, imitating a caddis taking flight.
The Evening Specialist – The J:son Caddis Adult 1 in Brown is a large, high-profile dry fly measuring 25 mm in length. Tied on a size #12 hook, this pattern is specifically designed to match the darker caddis species that frequently appear during evening hatches. The deep brown coloration provides a solid, clear silhouette against the water’s surface, making it an easy target for fish feeding in low-light conditions.
Crafted with J:son’s revolutionary air-filled wings and a segmented foam body, this fly is built to stay afloat through the roughest currents. Its superior buoyancy allows you to utilize the "racing boat" technique—pulling and skittering the fly across the surface to create the wake that triggers predatory instincts in large trout and grayling. For the angler who fishes late into the night or in tannin-stained waters, the 25 mm Brown Caddis is an indispensable imitation that delivers both realism and extreme durability.
