Which characteristic is true about the adults of flesh flies?

Flesh flies are known for their unique reproductive behavior, which sets them apart from many other fly species. Instead of laying eggs, adults of flesh flies deposit living larvae, also known as maggots, onto suitable substrates, often where decaying organic matter is present. This characteristic allows the larvae to feed almost immediately upon hatching, which may increase their chances of survival.

The presence of flesh flies is often associated with decaying flesh or carrion, where they find adequate food sources for their larvae. While they do often enter homes and can be found around decomposing matter or animal manure, the defining trait that distinguishes adults of flesh flies is their method of reproduction—directly depositing small maggots instead of laying eggs.
