Larimer's Yellow Sallie
Possibly the perfect searching pattern for western streams!
Little yellow stoneflies comprise several different species that hatch from early May into early August, depending on elevation and location. Most are size 14/16. Apparently these small stones taste good to trout, because when they are on the water, a pattern that mimics them is a great searching dry fly, even during periods of time when no insect activity is apparent. The Yellow Sallie, originated by popular Oregon fly fishing guide Tom Larimer, is such a pattern. And since Sallie is easy to see and incorporates floating foam into the construction, it makes a perfect dry fly from which to suspend a sunken nymph.
