Plataspidae), in connection with mycetophagous
halffterorum Edmonds, which may be exclusively mycetophagous
(Hinton 1935, Halffter & Matthews 1966, Edmonds 1979), though this species may also be attracted to carrion (Edmonds 1994).
Despite their ubiquity in nature, few studies have been conducted worldwide to determine the ecological importance of mycetophagous
diptera (fungi-feeding flies).
This species, along with Aradus antennalis Parshley which occurs in the western United States and Canada, is unusual among the North American Aradus species in that it is thought to feed on living pines, whereas the remaining 82 species occur on dead trees and are thought to be mycetophagous
(Usinger & Matsuda 1959).
