Overview

Tomsu’s Ultra Mouse is a masterfully designed topwater fly that combines realistic detail with fish-triggering movement to imitate a swimming mouse or rodent. Developed by fly designer Rick Tomsu, this articulated pattern is crafted with a blend of synthetic and natural materials that not only mimic the silhouette and texture of a mouse but also float high and move naturally across the water’s surface. The articulated tail, durable body, and lifelike profile make it especially effective when targeting predatory fish such as trout, bass, and pike.

What sets the Ultra Mouse apart is its true-to-life design: the realistic body shape, tail movement, and visible ears give it the full profile of a struggling rodent. It skitters, wakes, and swims with subtle motion that provokes violent surface strikes, especially at dawn or dusk. The use of foam in the head and body ensures long-lasting buoyancy, while the tail is designed to flow naturally behind the fly, adding to its irresistible appeal.

Available in two sizes—2 and 6—Tomsu’s Ultra Mouse is ideal for a wide range of fishing situations, from tight riverbanks where trout patrol the edges to open lakes where bass crush surface prey. Whether you're casting it upstream into a cutbank or skating it across a weedy flat, this fly delivers heart-pounding takes and consistent results.Read More +
