"The issue of multiple mating by females is a long-standing conundrum in biology," adds Göran Arnqvist, an evolutionary biologist at Uppsala University in Sweden, who was not associated with the study.
Mating behaviour and the extent of multiple mating by male and female individuals are important components of life-history traits.
