Flies typically fertilize their eggs through a process called copulation, where the male transfers sperm to the female using specialized reproductive organs. After mating, the female stores the sperm in a structure called the spermatheca and later uses it to fertilize her eggs as she lays them. Depending on the species, flies may lay their eggs in various environments, often selecting locations that provide food or shelter for the larvae once they hatch.
