Sperm Competition in Butterflies

The book delves into 30 years of research on butterfly sperm competition, highlighting the reproductive strategies of both sexes. It examines how female butterflies, which typically mate multiple times, influence male mating tactics, including adaptations to prevent competition from other males' sperm. A significant focus is placed on the role of apyrene sperm and the implications of sperm dimorphism in competition. This comprehensive study offers insights into sexual selection and is particularly valuable for students of behavioral ecology.
