	P1′	Fecundity-D	Refractoriness	P2′	Fecundity-O
Fecundity-D	0.205*
Refractoriness	0.217*	0.083
P2′	0.706**	0.114	0.027
Fecundity-O	0.038	−0.158	−0.015	0.134

In defense tests, the experimental male was the first male to mate. P1′ is the proportion of offspring sired by the first male. Fecundity-D is the total fecundity of doubly mated females in the defense tests. Refractoriness is the proportion of females that did not remate. In offense tests, the experimental male was the second male to mate. P2′ is the proportion of offspring sired by the second male. Fecundity-O is the total fecundity of doubly mated females in the offense tests. Remating is the proportion of females that remated. *P < 0.05, **P < 0.01 (significant after Bonferroni correction), ***P ≤ 0.001.
