Scientists have been pondering why is a fly born? The tsetse fly is a common culprit in the spread of sleeping sickness, but researchers at the University of California, Davis, are trying to learn more about this strange reproduction process to create new ways to fight the disease. In less than a minute, the mother fly pushes out a larva almost as big as the adult fly. The researchers were reminded of a clown car when they first observed the larva.
The larvae of flies are white, but have darker outer shells. After emerging from the pupa case, a female fly can breed in less than 48 hours. Female flies can reproduce up to five times in one lifetime. During this time, flies will lay eggs in a suitable location.
The larvae of a fly feed on the dead bodies of other insects. After hatching, the larvae spend three to five days feeding. During this period, they also molt several times and burrow into their food source. After this, they are ready for the next stage of their life cycle.
The development of flies involves four different stages. The first stage is the egg, which flies lay in warm manure. The larvae develop into maggots, and finally become adult flies. Flies develop rapidly during the summer months. Most species will develop in seven to 14 days.
