Pond fishing requires decisions. Are you fishing for bass, bluegills or some other species? That decision determines your fly choices. Large bass prefer a sizeable meal followed by days of fasting. Bluegills feed regularly but due to their mouth size they require small (sizes 12, 10, 8) flies. But don’t overlook selecting “cross over” flies sized to attract both small bass and large bluegills. Sizes-8 and -6 flies sized to attract both small bass and large bluegills. Sizes 8 and 6 enable you to target both species simultaneously.
