Mycetaulus polypori
Melander, 1924
Mycetaalus polypori is a small fly in the Piophilidae, described by Melander in 1924. The epithet suggests an association with polypore fungi (bracket fungi), though specific ecological relationships remain poorly documented. Like other piophilids, it likely inhabits decomposing organic matter. Published biological studies on this species are scarce.

Identification
Identification requires examination of male genitalia and subtle characters of and leg chaetotaxy. Distinguished from by specific arrangements of bristles on the fore and details of the surstyli and hypandrium in males. External is unremarkable; body small (approximately 3–4 mm), dark-colored, with reduced wing venation typical of the . Accurate determination necessitates reference to Melander's original description (1924) and subsequent taxonomic revisions of Mycetaalus.
Habitat
Inferred from epithet and : associated with fruiting bodies of polypore fungi (Basidiomycota) on decaying wood. Has been recorded from forested environments where bracket fungi occur on dead hardwoods and conifers.
Distribution
Documented from North America; specific regional records require verification from primary literature. The 16 iNaturalist observations suggest scattered records but do not establish a reliable range map.
Host Associations
- Polyporaceae - probable association epithet and suggest larvae develop in or on bracket fungi, but this has not been experimentally confirmed
Similar Taxa
- Mycetaalus bipunctatusSimilar size and general appearance; distinguished by male genitalic structure and details of thoracic bristle arrangement
- Other PiophilidaeExternal convergent across ; requires dissection for definitive identification
More Details
Taxonomic note
The Mycetaalus is small and morphologically homogeneous; limits were historically based on subtle genitalic differences that may require reevaluation with molecular data. No molecular sequences are currently available for M. polypori in public databases.
Research needs
Basic including larval feeding habits, complete distribution, and remain undocumented. The association with polypore fungi implied by the name has not been verified through rearing studies or detailed field observation.
