Age specific insemination success of male Mexican fruit flies, Anastrepha ludens measured as the proportion of females to lay eggs that produced larvae, when full diet was provided from eclsoion until death (full diet always), when it was delayed until age 21 days, prior to which sugar diet was provided (full diet delayed), and when only sugar diet was provided (sugar diet). The line is the average proportion of males to exhibit successful insemination across all diets at each age with error bars representing the standard error about the mean at each age.
