Adults usually live 15 to 25 days, but may live up to two months. Without food, they survive only about two to three days. They require food food before they will copulate, and copulation is completed in as few as two minutes or as long as 15 minutes. Oviposition commences 4 to 20 days after  copulation. Female flies need access to suitable food (protein) to allow them to produce eggs, and manure is not adequate.
