How many eggs a pigeon lay in its lifetime?

Each female fly can lay approximately 500 eggs in several batches of about 75 to 150. The eggs are white and are about 1.2 mm in length. Within a day, larvae (maggots) hatch from the eggs; they live and feed in (usually dead and decaying) organic material, such as garbage or faeces. They are pale-whitish, 3-9 mm long, thinner at the mouth end, and have no legs. They live at least one week.
