Introduction. The name of each listed species is followed by up to five sources that report the species as occurring in Michigan. Sources in all upper-case letters refer to specific insect collections: MSU-ARC refers to material held by the Michigan State University Arthropod Research Collection (data provided by G. Parsons). All others refer to collection data extracted from the Symbiota Collections of Arthropods Network (SCAN) database online at https://scan-bugs.org/. See the Methods page for a list of abbreviations and associated collections.
Species names preceded by a single '?' are considered probable (for occurring in Michigan) but uncertain records. Those preceded by '??' are considered possible but unlikely to occur in Michigan. Species that are fully accepted as having valid Michigan records are unmarked. Species reported in the literature that we consider to be erroneous Michigan records are in a separate list following the others.
What was the tribe Mycetoporini in this subfamily is now considered to be its own subfamily, Mycetoporinae.

The following species were also reported from Michigan, but we consider them to be adventive, misidentifications or other errors:
Tribe Tachinusini
Nitidotachinus horni (Campbell, 1973): Herman (2001); only MI record is a middle Holocene fossil (Morgan et al., 1985)
Tachinus pallipes (Gravenhorst, 1806): Andrews (1923); a European sp. that prob. does not occur in NA
Tribe Tachyporini
Tachyporus chrysomelinus (Linnaeus, 1758): Andrews (1923), Hatch (1925), Hubbard and Schwarz (1878); a Eurasian sp. believed to not be in N.A. (Herman, 2001); WI, PA, & ON records all probably misidentifications according to Campbell (1979)
