Many stoneflies are big. That makes them an attractive food source for big trout This is purely anecdotal, but most of the big trout I’ve caught in my life have eaten streamers or stoneflies. The size of the imitations also lends itself to building in weight, making the flies serve double duty as both weight and bait.
