Experiments with Stomoxys calcitrans adults showed that different blood diets markedly affect the lifespan and reproductive potential of this species. When fed on blood from herbivores (cattle, sheep, goat, horse and donkey) the adults lay more eggs than they do when fed on blood from omnivores (pig). Blood from carnivores (dog) is even less suitable than that from omnivores, and no eggs are laid when the flies are fed on chicken blood.
