Whether they are flashy or bright, attractor flies are a category of patterns designed for prospecting for fish in unknown areas of water. Fly anglers don’t always know what is ‘hatching’ or what fish are focusing in on. Instead of guessing what ‘natural’ pattern will work, the next best strategy is to fish with flashy patterns meant to catch their attention and urge them into opportunistically taking the fly. The overall versatility of attractor patterns also allows anglers to fish one flashy fly and cover a whole variety of aquatic insects and food sources.
