Life Cycle of the Fly
Mouse over or click cycle items
Adult
- Three days after emerging, female flies begin to mate and can lay eggs as soon as 2 days after mating.
- Adult female flies can live over 30 days in the field under ideal conditions.
- The life cycle of the screwworm is about 21 days in favorable environments.
Eggs
- Eggs are laid on or near an open wound or bodily orifice of a warms-blooded animal. A wound can be as small as a tick bite.
- On average, a female lays 200-300 eggs in a single egg mass or the egg mass may be split between several locations. Screwworms only lay their eggs on living animals.
Larvae
- The eggs hatch into larvae after 10-12 hours.
- The larvae are of a clear color and burrow into the wound to feed, causing further damage to the host.
- After feeding for about a week on the wound, the larvae fall off and burrow (about 2.54 – 5.08 cm deep) in the soil to pupate.
Pupae
- In the tropics, the incubation period is typically of 7 – 10 days.
- The pupae can live in the soil for several months if the temperature is cooler.
- Male flies typically emerge first.
