Malloch, 1916
Hydrotaea houghi is a of muscid fly described by Malloch in 1916. It belongs to the Muscidae, which includes house flies and related species. The species has been recorded from Hawaii and the continental United States. As a member of the Hydrotaea, its larvae are known to be predatory on other fly larvae in manure and decaying organic matter.

Identification
Hydrotaea houghi can be distinguished from other Hydrotaea by subtle morphological features of the male terminalia and chaetotaxy (bristle arrangement). Accurate identification requires examination of specimens under magnification, preferably by a dipterist familiar with the . The species lacks the distinctive external color patterns that characterize some related muscids.
Habitat
Breeds in decaying organic matter, particularly animal manure and rotting vegetation. Associated with livestock operations where moist manure accumulates.
Distribution
Recorded from Hawaii and the continental United States (North America).
Diet
Larvae are predatory, feeding on other dipteran larvae including horn fly (Haematobia irritans) larvae developing in cattle .
Life Cycle
Complete with , larva, pupa, and stages. Larval development occurs in moist organic substrates. Specific timing of life stages for this is not documented.
Behavior
Larvae actively prey upon other fly larvae in shared breeding substrates, particularly manure. This predatory has been documented in the Hydrotaea as a mechanism for pest flies.
Ecological Role
Predatory larvae contribute to natural suppression of horn fly and other pest fly in cattle . Acts as a agent within the dung fauna .
Human Relevance
Considered beneficial in livestock pest management due to predatory larvae that reduce of economically important flies such as horn flies. No known negative impacts documented.
