The foam beetle fly pattern is easy to tie and is a top producer during the summer months, especially near overhanging trees. Trout love to eat beetles that are blown into the water. Tie this pattern in sizes 12-18. Black tends to be most effective, but you will find success with olive and brown versions.
This is a very good all around fly for brookies, rainbow trout, bass, crappie and very effective for bluegill and other possibilities.
