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-Olive Precision Tool – J:son Mayfly Spent 5 Olive Grey (Hook #24) The Olive Grey Spent #24 is specifically engineered for the most demanding fishing situations where trout and grayling are keyed in on the smallest olive-colored mayflies or midges. In size #24, this imitation mimics those tiny, translucent insects that often appear as almost invisible specks on the water surface. The subtle olive-grey tone is perfect for matching the fading colors of a dying micro-spinner in its final life stage.
Achieving high buoyancy and a realistic silhouette in such a small fly is only possible through J:son’s advanced foam construction. The wings lay perfectly flat to create the "T-silhouette" that selective fish demand. We know it can be nearly impossible to thread the leader through the eye of a traditional #24 hook; therefore, even though the hook itself is a #24, we have ensured the hook eye remains at least a size #18. This technical advantage allows you to present this extreme micro-pattern with confidence and ease, even during the most technical hatches in crystal-clear water.
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.
