Fig. 1. The relationship between the number of fertile (open circles) and
non-fertile (filled circles) sperm present in the female's sperm storage organ
and the tendency to remate in the butterfly Pieris napi. Females that
did not remate within 10 days following their initial copulation stored
significantly more non-fertile sperm compared to remating females, whereas
there is no difference in the number of fertile sperm stored. Values are means
± S.E.M. (redrawn after
Cook and Wedell, 1999 ).
