Hippelates flies are known for which of the following attributes?

Hippelates flies are particularly noted for their attraction to the eyes and mucous membranes of hosts, which is a defining behavior of this genus of flies. This tendency makes them nuisance pests, as they can cause irritation and discomfort to humans and animals. Their feeding habits involve landing on moist surfaces, including the eyes, where they can also lay eggs, thereby increasing their chances of spreading pathogens.

In contrast, the other attributes listed do not accurately describe Hippelates flies. These flies are not known to bite humans, which differentiates them from other biting fly species. Although some insects are attracted to light, Hippelates flies are more specifically known for their habits related to moisture rather than light attraction. Additionally, while many flies do breed in various substrates, Hippelates flies are not typically associated with breeding in soil; their breeding habitats are usually more closely linked to organic material or decaying matter where moisture is present.
