How long does it take for fly eggs to become larva?

The correct answer is that it takes approximately 24 hours for fly eggs to develop into larvae, commonly known as maggots. This rapid development is part of the life cycle of many fly species, particularly the common housefly.

After the female fly lays her eggs, the eggs undergo a process of embryonic development and hatch into larvae within this short time frame. Warm environments can expedite this process, as flies thrive in warmer conditions, which can quicken the hatching time. The quick transition from egg to larva is essential for flies because it allows them to take advantage of available resources in their environment, such as decaying organic matter, which is crucial for their growth and further development into adult flies.

The other time frames provided in the choices do not accurately reflect the typical duration for this particular stage in the fly life cycle, making 24 hours the most accurate and recognized timeframe.
