Do black flies and deer flies breed in garbage and manure like house flies?

Black flies and deer flies have distinct breeding habits that set them apart from house flies. Unlike house flies, which are notorious for breeding in decaying organic materials, such as garbage and manure, black flies and deer flies primarily breed in freshwater environments. These insects thrive in clean, flowing water bodies, where they lay their eggs, generally attaching them to submerged rocks and vegetation.

House flies are attracted to decomposing matter, which provides a nutrient-rich environment for their larvae. In contrast, the life cycle of black flies and deer flies does not rely on such substrates, hence their breeding habits are not associated with urban waste or agricultural byproducts like manure. This fundamental difference in habitat requirements highlights why these flies do not breed in garbage and manure, validating the assertion that the answer is false.
