比较了交配成功雄蝉与交配失败雄蝉的特征。在野外，成功的雄性比不成功的雄性体型更大，飞行肌肉质量与身体质量（飞行肌肉比）的比例更高。成功雄鼠飞行肌比的升高不是由于精液转移到雌鼠身上，也不是由于异速生长效应。在自然界中，高飞行肌比的大型雄性飞禽在大多数条件下取得成功的原因可能是其较好的守地盘能力和飞行机动性。然而，时间或环境条件也可能存在，使小雄性偶尔有机会交配。
The characteristics of successfully mating male cicada killers (Sphecius speciosus Drury) were compared to those of unsuccessful males. In the field, successful males were larger and had higher ratios of flight muscle mass to body mass (flight muscle ratios) than unsuccessful males. The elevated flight muscle ratio of successful males was not because of semen transfer to the female nor because of an allometric effect. Better territory-holding ability and flight maneuverability probably contribute to the success of large males with a high flight muscle ratio in nature under most conditions. However, temporal or situational conditions may also exist whereby small males may occasionally have opportunities to mate.
