The Royal Trude and Lime Trude can represent a variety of insects, including grasshoppers and caddisflies. The down wing pattern provides an attractive silhouette. Trude patterns often work when other trout flies seem to be ignored by picky fish. This pattern has been around since the early 1900's when Alfred Trude first started using them on the Henery's fork of the Snake River near Island Park, Idaho. Great pattern for all waters representing a wide variety of insects.
