Streamers & Woolly Buggers are flies which represent minnows, bait fish, leeches, crayfish and other food forms. Flies which imitate these swimming aquatic critters can be presented using similar techniques. All of these creatures have the ability to swim through the water and are preyed upon by trout. There are times when a streamer or & Woolly Bugger will take trout when nothing else will work. Egg Patterns are great any time but are best when there are spawning fish and others are feeding on the eggs.
