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 genus Ctenicera has recently been divided into several genera. According to BugGuide only kendalli will remain in Ctenicera, but to date virens has not been assigned to a new genus, thus it is still listed as Ctenicera. In addition, if acutipennis has been assigned to a new genus, we have not found that information.
Ampedus deletus is considered a junior synonym of Ampedus pedalis by some (e.g., Poole and Gentili 1996, Peck and Thomas 1998), but both species are recognized as distinct in other publications (e.g., Bousquet et al. 2013, Majka and Johnson 2008). We list both from Michigan.
