What is the general life cycle progression of flies?

The correct sequence for the general life cycle of flies is the progression from egg to maggot (larva), followed by the pupae stage, and finally to the adult. Flies typically start their life cycle as eggs, which can be laid in decaying organic matter or other suitable environments.

Once the eggs hatch, they develop into larval forms, often referred to as maggots. These larvae feed on the substrate in which they were laid, undergoing growth and multiple molts. After sufficient feeding and growth, the larvae transition into the pupae stage, where they undergo metamorphosis.

In the pupal stage, flies undergo significant transformation before emerging as adults. This cycle allows for rapid population growth in suitable environmental conditions, which is why flies can often be seen in large numbers.

The other choices do not correctly represent the typical life cycle of flies, as they may omit essential stages or misrepresent the terminology used for larval forms.
