Pink Squirrel

he Pink Squirrel is a Driftless classic for a reason. Designed to imitate a broad range of small aquatic invertebrates, it blends the profile of a scud, caddis larva, and general nymph into one simple, effective pattern. Rather than matching a single bug, it represents the kind of high-protein food trout encounter constantly in limestone streams.

The Driftless region is dominated by cold, spring-fed creeks with stable flows, abundant vegetation, and nutrient-rich water. These conditions support large populations of scuds, sowbugs, and caddis larvae—exactly what the Pink Squirrel suggests. The pink hotspot isn’t about color matching; it acts as a trigger, imitating eggs, exposed flesh, or oxygen-rich invertebrates, and helps trout locate the fly in broken water without spooking them.

Fished near the bottom with a clean dead drift, the Pink Squirrel excels as a point fly or as part of a two-fly nymph rig. Its natural tones blend in seamlessly with Driftless substrates, while the subtle pink accent provides just enough contrast to turn interest into strikes. In a region where trout feed opportunistically and consistently, the Pink Squirrel remains one of the most reliable flies you can tie on.
