The Bugzilla is a exactly that. Its something from out of the world. But I tell you when you need that type of fly that can simulate a range of large insects on the surface. these are well worth a drift or two. They offer a perfect balance of a cicada or hopper imitation. They are a natural variant which I love. They are also a nice and buoyant dry fly but recommend adding flotant to keep them high on the water surface. When the fish are looking up and eating big insects. it's time to pull these out of the bag.
