Bugs and Poppers (or Bass and Panfish flies) are generally designed to resemble both surface and sub-surface insect, crustacean, baitfish prey consumed by warm-water species such as Largemouth bass or bluegill. This genus of flies generally includes patterns that resemble small mammals, birds, amphibians or reptiles that may fall prey to fish, or in the case of panfish flies, small aquatic insects or crustaceans.
