Sexually cannibalistic mating systems provide an excellent opportunity to examine and gain a better understanding of male mate choice, that is, mate choice between two or more individuals and/or the more extreme form of choice that manifests as mate rejection.
[M]ales rarely rejected poor-condition females in the more ecologically relevant scenario of only one immediate mating opportunity.
This lack of male mate choice… may be partially explained by the strong/intense scramble competition selecting for efficient mate location…; the cost of not finding a female may exceed the cost of not being choosy.
