Where do house fly larvae typically develop?

House fly larvae, commonly known as maggots, typically develop in nutrient-rich organic materials where they can feed and grow. This environment is usually found in decomposing matter, particularly animal waste and rotting fruits and vegetables. These materials provide the necessary sustenance for the larvae to thrive, as they require a moist and rich source of food to develop properly.

The choice referring to clean environments does not apply because house flies are often associated with unsanitary conditions where decaying organic matter is present. Developing exclusively in water is inaccurate, as while larvae may require moisture, they need a food source that is found in decomposing organic materials rather than just water. Lastly, the notion of larvae developing in dry places contradicts their need for moist environments, as larvae require a certain level of humidity to survive and they thrive in wet, decomposing organic materials. Hence, the correct choice highlights the essential conditions that support the growth of house fly larvae.
