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 High-Contrast Trigger – The J:son Caddis Adult 3 in Cinnamon Brown / Apple Green is a precision-engineered dry fly with a 17 mm profile, tied on a size #18 hook. This specific color combination is a deadly trigger for trout and grayling, mimicking the distinct "Apple Green" body found in many sedge species, contrasted with natural "Cinnamon Brown" wings. This pattern is particularly effective for imitating egg-laying females or newly hatched adults where the bright internal body color is clearly visible to the fish from below.
Crafted for maximum buoyancy, this fly utilizes J:son’s revolutionary air-filled wings and a flexible foam body, making it essentially unsinkable. The #18 hook size makes it a perfect choice for technical water where fish are selective about size but responsive to strong color cues. Whether you're dead-drifting in a quiet pool or skating it across a riffle to mimic a "racing" insect, the Cinnamon Brown / Apple Green Caddis is a technical powerhouse for your summer fly box.
