Topwater lures, also known as surface lures, are fished by casting and retrieving and most of them require proper presentation to be effective. These hard baits are called poppers, chuggers and walkers and they imitate frogs, cicada, insects, ratts, little birds and other nonaquatic species. Topwater lures cover the surface and trigger strikes from curious fish below while swimbaits try to pick off fish by matching the hatch.
