Habitat

Distribution
Records from iNaturalist suggest a Holarctic distribution with observations from North America and Eurasia. Specific range boundaries for the remain poorly documented.
Ecological Role
As members of Scathophagidae, in this likely contribute to nutrient cycling through larval development in decomposing organic substrates. The is generally considered beneficial in agricultural contexts due to accelerated breakdown of and reduction of pest fly .
