There are another three important fish hitting triggers incorporated into the Muncher Nymph, but as folk like to rip-off fly patterns, the only way you are going to find out what those other triggers are, is to purchase a few and then take a long hard look at the flies. Just remember that when no fish are showing, and in a wide range of conditions, the Muncher Nymph will consistently produce fish. The Muncher Nymph has produced fish from Alaska down to Arkansas, all-across Canada, Australia, Europe, Asia, the United Kingdom, Ireland and Scandinavia.
