Juracek Emerger
This pattern originated by John Juracek can probably be best described as a floating nymph. Flies of this type can be very effective when trout are keying on emergers as opposed to duns, a situation that is common during heavy hatches. Use synthetic dubbing for the body. The thorax is tied much fuller than the abdomen. The fly should be dressed and fished as a dry fly.
