Another surface fly that will ring the bluegill's dinner bell is Bruce's Foam Beetle. This is tied with the bluegill's favorite color -- yellow. Just as the smallmouth bass has its favorite color (which is chartreuse), bluegills seem to find yellow irresistible. The main ingredient of this fly is a yellow closed cell foam body with grizzly hackle for legs. It is a simple, quick fly that will withstand the ravages of a lot of fish without needing any repair or floatant.
