Adult Caddis – Quick Guide
Why the Adult Caddis matters:
-
Movement: Unlike mayflies, caddis "skate" and "skitter" on the surface, creating a V-shaped wake like a small racing boat.
-
The Trigger: This frantic movement often causes aggressive, explosive rises from trout and grayling.
-
Key Moments: Most effective during a hatch or when females return to the water to lay eggs.
J:son Caddis Adult 4 Black (#20)
Micro Precision for Selective Fish The J:son Caddis Adult 4 Black is our smallest adult 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:
-
High Contrast: The solid black color creates the sharpest possible silhouette against the sky, making it easy for fish to spot.
-
Unsinkable: Features J:son’s signature air-filled wings and foam body. It stays afloat even in choppy water.
-
Realistic Action: Designed to be "skated" or twitched. Its buoyancy allows it to create a lifelike wake without drowning.
-
Perfect for Midges: Often doubles as a great imitation for small black midges or terrestrial insects.
Pro Tip: Use this fly when the water is crystal clear or when you see tiny, dark insects "racing" across the surface.
