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.

Sikes et al. (2013) argue that the Nicrophorus species found across all of northern North America, and which has been considered conspecific with the palearctic N. vespilloides Herbst, is in fact a distinct species. They resurrected the name N. hebes (Kirby) for this species. BugGuide (as of Feb. 2022) still uses N. vespilloides.

The following species were also reported from Michigan, but we consider them to be adventive, misidentifications or other errors:

Subfamily Nicrophorinae

Tribe Nicrophorini

Nicrophorus guttula Motschulsky, 1845: Townsend (1889) as Necrophorus guttula Mots.; a western sp. that does not occur in MI

Nicrophorus obscurus Kirby, 1837: Hubbard and Schwarz (1878) as Necrophorus obscurus Kby.; a Great Plains sp. that should not be in MI

Nicrophorus vespilloides Herbst, 1783: Peck and Miller (1993), Andrews (1923), Hatch (1924), Hubbard and Schwarz (1878); what has gone as vespilloides for many years in most of N.A. is now considered hebes (Sikes et al, 2016)
