Flies can live for about a month in the wild, but in captivity they can live for much longer. A female fly can lay up to 500 eggs in her lifetime. The eggs will eventually hatch and become full-grown flies. The lifespan of flies varies by species, but they usually live for about two or three days without food. If they can obtain adequate amounts of water and nutrients, they can live for several weeks. Flies also require food before copulation, which takes about two to 15 minutes. Female flies need protein and can’t get this from manure.
During the winter, flies spend a long time in the larval stage. When the weather gets warmer, the nymph stage completes its development and emerges as an adult fly. However, flies don’t live as long as they once did. During the spring and summer months, adult flies spend about thirty to sixty days in the pupae stage.
A fruit fly’s life cycle takes between two and four weeks. A fruit fly’s larval stage lasts a few days or a week, depending on the temperature. The pupae stage of the fruit fly takes two to six days, depending on the ambient temperature.
