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.

Bouchard (2011) has only two subfamilies for this family with all of the subfamilies used in Arnett et al. (2002) reduced to tribes within the Coccinellinae; however, they pulled the Microweiseini out of the Sticholodinae and raised that group to subfamily level.  BugGuide continues to follow Arnett et al. (2002), and that is what we have done here also.

BugGuide recognized no subspecies for Coccinella transversoguttata whereas GBIF has three.  We follow Gordon (1985) and use a subspecies name for the Michigan population.
