Which of the following is true of the stable flies' larvae?

The correct answer is that stable flies' larvae thrive in decomposing straw and compost. This is significant because stable flies are known to prefer organic materials that are rich in nutrients and moisture, which are commonly found in decaying plant material. Decomposing straw and compost provide an ideal environment for their larvae to develop, as these materials offer warmth, moisture, and a source of food.

Stable fly larvae are not typically associated with human waste or dairy waste exclusively, and while they may occasionally be found in such substrates, they are not limited to them. They also do not require water bodies for development, as larvae can thrive in a variety of organic matter as long as the environmental conditions are suitable. Understanding the preferred habitats of stable fly larvae is crucial for effective pest management and control strategies.
