The Micro Finesse Stone Fly is the exact replica of a plecoptera larvae in soft plastic form. Eurotackle is the first company to make an insect soft lure 100% realistic and providing so much action. The vibrations created by the Stone Fly are identical to the ones a live plecoptera larvae would make in the water. The tail and legs of this bait will create micro vibration which will attract all kinds of fish like perch, crappie, panfish, and trout! For the first time in your life, you'll be able to use a well-designed ultra light bait made out of an extra soft plastic that is still very durable! Each Stone Fly measures 1.2" and comes in a pack of 8.
