Seasonal Behavioral Plasticity

摘要

The African butterfly Bicyclus anynana shows a sex-role reversal in courtship behavior, which is set during larval development and controlled by larval rearing temperature. In the wet season form, the males court and the females choose, while in the dry season form, females court and males choose. Prudic et al. (p. 73) show that these changes in mating behavior correlate with a cryptic change of the sexual ornament in both sexes. In the wet season, males have brighter sexual signal in the ultraviolet (UV) range, and in the dry season, females have a brighter sexual signal in the UV range.
