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 Essential – The J:son Caddis Adult 2 in Brown is a masterfully crafted dry fly with a 21 mm profile, tied on a size #14 hook. This size and dark brown coloration are specifically chosen to mimic the numerous medium-sized, dark-bodied sedges that hatch in abundance during the late afternoon and evening. Its solid silhouette is highly visible to fish looking up through the surface film, especially in the low-light conditions when caddis activity is at its peak.
This fly is engineered for durability and buoyancy. Utilizing J:son’s patented air-filled wings and a segmental foam body, it is designed to be virtually unsinkable. This allows you to fish the fly actively—twitching and skating it across the water to create the characteristic wake of a living insect—without the fly losing its position in the surface film. For the angler who demands technical perfection and extreme realism in their dry fly selection, the 21 mm Brown Caddis is a top-tier choice for consistent success.
