 Female "D. anilis" are polyandrous and will often mate with several males while discharging a single batch of eggs.Females can store enough sperm for two egg batches, and therefore mating before each egg-laying is time-consuming and unnecessary, exposing females to risk of predation, disease, and injury during male-male conflicts.However, the multiple matings give the female access to the resources of territory-holding males, such as food and egg-laying sites, and mating with territory-holding males may allow the female to be defended while she lays her eggs.
