Females reliant on stored sperm had fewer offspring compared to remated females, but offspring size and short‐term growth rate did not differ. Thus, females may use stored sperm in cases such as previous mating with a preferred male, lack of access to mating opportunities during a reproductive cycle, or to maximize egg fertilizatio...
