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 higher classification of this family is unsettled.  BugGuide follows American Beetles (Arnett et al., 2002) whereas Bouchard (2011) uses a different system.  The subfamilies Calochrominae, Erotinae and Platerodinae of Arnett et al. (2002) are all reduced to tribes within Lycinae by Bouchard (2011), but the genus Dictyoptera which Arnett et al. (2002) have in Erotinae has been removed by Bouchard (2011) and placed in the tribe Dictyopterini within a new subfamily Dictyopterinae.  In our list, we follow the newer system of Bouchard (2011) for subfamilies.

The following species was also reported from Michigan, but we consider it to be adventive, a misidentification or other error:

Subfamily Lycinae

Tribe Platerodini

Plateros canaliculatus Say, 1835: Townsend (1889), Hatch (1924); Green (1953) says this name could refer to any of several species and we cannot know which
