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.

The following species were reported from Michigan, but we consider them to be adventive, misidentifications or other errors:
Frostia laticollis (LeConte, 1866): Wolcott (1909), Hubbard and Schwarz (1878); reported as Malthodes transversus Lec., a California sp. that cannot be in MI.
Malthodes exilis (Melsheimer, 1846): Hubbard and Schwarz (1878); a Texas sp. (?), not in Pelletier and Hébert (2014), many older publications used this name for a variety of species (Fender 1951)
Rhagonycha cruralis (LeConte, 1851): Hubbard and Schwarz (1878); reported as Telephorus cruralis Lec., a poorly known SE sp., should not be in MI
