If flies lay eggs that hatch into maggots do they then grow another fly?

Yes, flies lay eggs that hatch into maggots, which then grow into adult flies. This process is called metamorphosis.

1. Egg: The adult female fly lays her eggs on a suitable substrate, such as rotting meat or garbage. The eggs are small, white, and oval-shaped.

2. Maggot: The eggs hatch into maggots, which are small, white, and legless. Maggots feed on the substrate, and as they grow, they shed their skin several times.

3. Pupa: When the maggot is fully grown, it spins a cocoon around itself and enters the pupal stage. Inside the cocoon, the maggot undergoes a dramatic transformation, and its body changes into that of an adult fly.

4. Adult fly: The adult fly emerges from the cocoon and is now able to fly and reproduce.
