Red is such a deadly color and this newcomer Red WD40 is no exception it has quickly proved itself as the emerger pattern not to be without. The Red WD40 works well as an Emerging Midge Nymph pattern or Mayfly Emerger. The Red WD-40 is best fished on a dead drift as a Pupa Midge at the end of your drift lift your rod to bring your WD40 to the surface replicating the natural movement of the emerger. Try these out on your favorite tailwater or creek you won't believe the results.
