Description
When trout feed on Spent Spinners, they do it with comfort. These dead or dying mayflies will not fly away, making them an easy, high-protein meal. The rise is typically slow and methodical, often in a classic "head-and-tail" style. Many anglers find this stage difficult, as fish become extremely selective when hundreds of spent spinners blanket the surface.
Our Commitment: Perfect Imitation To succeed and perhaps hook the fish of a lifetime, you must observe where the fish feeds and ensure your presentation is flawless. But just as important is the imitation itself. Because the insect is stationary, the fish has plenty of time to scrutinize your fly.
Our commitment is to provide imitations of the real insect where the fly has the right shape, size, proportions, and colours, and, not least, leaves the correct print on the surface of the water. This imitation of an adult mayfly in the Spent stage possesses all the right properties. It looks natural, feels natural, and fish will eat it.

The Micro-Spinner Specialist – J:son Mayfly Spent 4 Black (Hook #22) When the hatch consists of the very smallest mayflies, such as tiny Caenis (the "Angler's Curse") or small Baetis species, the Black Spent #22 is your most important ally. These tiny insects often fall to the water in massive numbers, and despite their size, they can make the largest trout in the river completely selective. In this spent stage, their bodies appear as a sharp, dark needle-thin silhouette against the surface film.
In size #22, precision is everything. This fly captures the micro-proportions of the natural insect perfectly, with wings that lay flat to create the unmistakable spent profile. To solve the common struggle of rigging micro-flies, we have kept the hook eye at a size #18, allowing you to thread your leader with ease even during a frantic evening rise. J:son’s foam construction ensures that this tiny imitation stays afloat and balanced, providing a vulnerable and realistic target that fish can't resist.
Correct Surface Print: The imitation creates the precise flat-winged silhouette on the water film that triggers even the most selective fish.
Optimal Realism: Designed to mimic the spent, exhausted mayfly lying flush in the surface film after egg-laying.
High Quality: Exact proportions and biological colours that perfectly match the natural insect’s final life stage.
Pro Tip: Use a Swivel for Perfect Presentation Because J:son realistic flies are designed with anatomically correct wings, they act like small propellers in the air during casting. This can cause your leader to twist, leading to tangles and poor presentation.
To prevent this and ensure your fly lands perfectly every time, we strongly recommend using a J:son Anti-Twist Swivel. This simple addition will eliminate line twist and let you focus entirely on the fish.
