The Woolly Bugger is a very versatile pattern that will catch fish on virtually any lake or river. The marabou tail and in most cases a palmered body suggest succulent small juvenile bait fish, insect larva, tadpoles or leeches that trout, bass and steelhead devour.The Woolly Bugger is tied in a variety of color combinations,usually natural ones such as black, brown, and olive,and can imitate anything from a leech or dragonfly nymph to a small fish. The black and olive version is particularly effective.
