Most fly anglers alread have small beetles in their fly boxes (and if they don't, they probably should). But you don't' often see beetle flies in the larger sizes even though these larger bugs are abundant along most river banks. RIO's Ground Beetle features an irridescent underbody, rubber legs and a foam sighter...but it also has a beautiful shell back that has been protected with a flexible uv coating for durability. Beetles make wonderful searching bugs if you don't know what is hatching.
