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 Saffron Gold / Pistachio Green (#20)
The Bright-Day Specialist The J:son Caddis Adult 4 Saffron Gold / Pistachio Green is a masterfully crafted micro-fly with a 13 mm profile, tied on a size #20 hook. This vibrant color palette is designed to mimic the lighter, more colorful caddis species that often dominate the water during bright, warm summer days.
Why this fly works:
-
Summer Triggers: The combination of Saffron Gold and Pistachio Green perfectly replicates the translucent internal colors of many small sedges and their egg sacs.
-
Unbeatable Buoyancy: Features J:son’s patented air-filled wings and a foam body, ensuring the fly stays floating high even in choppy surface conditions.
-
Action-Ready: Its superior buoyancy allows you to "skate" or twitch the fly across the surface to imitate the frantic movement of a living insect without it drowning.
-
Micro-Technical Performance: The #20 hook size is ideal for technical fishing in clear water where trout and grayling have plenty of time to inspect your offering.
Pro Tip: This color is highly visible to the angler in bright sunlight. It is an excellent choice for summer afternoons when you need a fly that stands out both to the fish and yourself.
