How long does it typically take for flies to complete their life cycle from egg to adult?

The typical life cycle of flies, particularly common species such as houseflies, generally spans from 7 to 14 days from the egg stage to adulthood. This timeframe includes the various developmental stages: egg, larva (or maggot), pupa, and finally, adult. Each stage takes a specific amount of time, influenced by environmental factors like temperature and humidity, which can accelerate or decelerate the process.

This answer highlights how the life cycle duration is adaptive, allowing populations to thrive under optimal conditions. Understanding this lifecycle duration is critical for pest management strategies, as it informs the timing of control measures to effectively break the cycle and reduce fly populations. Other timeframes provided do not accurately reflect the biological development of most common flies.
