Description
Imagine a fish's perfect meal: a helpless, struggling insect on the verge of its final transformation. That is exactly what the mayfly emerger represents. It is not a dry fly, nor is it a nymph—it is the critical, in-between stage that drives fish into a feeding frenzy.
This fly imitates a mayfly as it breaks free from its nymphal shuck and begins its perilous journey to the water's surface. It is a moment of immense vulnerability for the real insect and a moment of unmatched opportunity for the angler. Fish know this is the easiest meal of the day; they see a nutrient-rich target that isn't fast enough to escape and isn't quite ready to fly away. When a hatch is on and fish are rising but refusing traditional dry flies, an emerger is often the secret weapon that turns a frustrating day into an unforgettable one.
The Ultimate Micro-Emerger – J:son Mayfly Emerger 5 Light Olive (#22) The J:son Mayfly Emerger 5 in Light Olive is our smallest and most specialized emerger, designed for the most demanding technical situations. Tied on a tiny size #22 hook, this fly is a perfect imitation of the smallest mayfly species that often hatch in huge numbers, leaving fish completely focused on "micro-food." The Light Olive color offers a pale, translucent realism that is vital when fishing in clear water or under bright conditions.
Despite its ultra-small size, we have designed this fly with the angler’s convenience in mind: the hook eye is no smaller than a size #18, making it much easier to thread your leader even in difficult conditions. This micro-pattern retains all of J:son’s anatomical realism, sitting low in the surface film to create a perfect "stuck-in-the-film" silhouette. When fish are rising with barely visible sips to tiny insects, the #22 Light Olive Emerger is the ultimate solution for the serious match-the-hatch angler.
