Which statement about house flies is TRUE regarding their reproductive habits?

The statement that house flies' females mate and deposit 4 to 6 batches of 75 to 150 eggs on moist manure is accurate and reflects their reproductive behavior well. House flies are known for their high reproductive output, allowing them to rapidly increase their population under suitable conditions.

Typically, female house flies seek moist organic matter, such as manure, for laying eggs. This choice is critical as the developing larvae, or maggots, require a nutrient-rich environment to thrive and eventually metamorphose into adult flies. By laying multiple batches of eggs, house flies can ensure higher survival rates for their offspring, as their larvae have immediate access to the food and moisture they require right after hatching.

In contrast, the other statements do not accurately represent the reproductive habits of house flies. They thrive in moist environments for egg-laying rather than dry ones and can reproduce many times throughout their lives, not just once. Furthermore, house flies are intrinsically linked to organic matter for breeding, as this is where they lay their eggs and where larvae can find critical nourishment.
