Summary: scored the distribution of glandular secre-
tion. The former, but not the latter, females
regenerated their patches (Mann­Whitney
U-test; P 0.002). Further, the lifespan of
starved males increased by about 50% when
they were kept with a female compared with
those kept alone (2.4 0.2 versus 1.6 0.2
days; t-test, P 0.014), but there was no sig-
nificant difference in survival when males
were fed (10.6 1.4 versus 13.1 1.6 days;
t-test, P 0.252; ANOVA interaction,
F1,79 3.99, P 0.049), suggesting that males

of a male did not significantly affect female
lifespan (15.5 1.9 versus 14.3 2.4 days;
