Distribution
of Anorostoma have been recorded in North America and the Palearctic region, with observations concentrated in temperate zones. Specific distribution data for individual species within the remains limited in available sources.
Ecological Role
As members of Heleomyzidae, in this likely contribute to nutrient cycling through larval development in decaying organic substrates, though direct ecological studies of Anorostoma are not documented in available sources.
