BH Zug Bug A bit old fashioned yesa | but the Bead Head Zug Bug is truly a great caddis nymph. Its peacock body is a great attractor color, and the fan tail is unique to this pattern. This bead head version adds weight and flash. Larger sizes also imitate Salmon/Stonefly nymphs as well. Fish this as a dropper! Available in sizes # 08 - # 20
