In the Japanese common grass yellow, Eurema mandarina , the mean survival period at 10 °C was 13.4 and 7.9 weeks for mated and unmated females, respectively. Morphological changes in the spermatophores removed from mated females suggest digestion of spermatophores by females. This result indicates that adaptive significance of pre‐overwintering copulation of females is acquisition of nutrients for overwintering.
