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.
BOSTRICHIDAE
3 subfamilies, 3 tribes, 8 genera, 16 species (plus 4 species reported for Michigan in error)
Subfamily Bostrichinae
Tribe Bostrichini
Amphicerus bicaudatus (Say, 1824): Fisher (1950), Hubbard and Schwarz (1878), MSU-ARC
Lichenophanes armiger (LeConte, 1866): Fisher (1950), Hubbard and Schwarz (1878), Andrews (1916), MSU-ARC
Lichenophanes bicornis (Weber, 1801): Fisher (1950), Andrews (1923), Hatch (1924), MSU-ARC
Lichenophanes mutchleri Belkin, 1940: Fisher (1950), MSU-ARC
Lichenophanes truncaticollis (LeConte, 1866): Fisher (1950), Downie and Arnett (1996), Hubbard and Schwarz (1878), MSU-ARC
Tribe Xyloperthini
Scobicia bidentata (Horn, 1878): Fisher (1950), Downie and Arnett (1996), Hubbard and Schwarz (1878), MSU-ARC
Xylobiops basilaris (Say, 1824): MSU-ARC, BugGuide, Haack (2020)
Subfamily Dinoderinae
Prostephanus punctatus (Say, 1826): Haack and Ruesink (2020), MSU-ARC
Rhyzopertha dominica (Fabricius, 1792): Ruppel (1977), MSU-ARC
Stephanopachys cribratus (LeConte, 1866): Fisher (1950), Downie and Arnett (1996), Hubbard and Schwarz (1878)
??Stephanopachys densus (LeConte, 1866): Downie and Arnett (1996), Hubbard and Schwarz (1878); an east coast & SE sp., MI record doubtful and needs confirmation
Stephanopachys rugosus (Olivier, 1795): Ruesink and Parsons (2021), MSU-ARC
Stephanopachys substriatus (Paykull, 1800): Hubbard and Schwarz (1878), Andrews (1923), MSU-ARC
Subfamily Lyctinae
Tribe Lyctini
Lyctus carbonarius Waltl, 1832: Hubbard and Schwarz (1878), MSU-ARC
Lyctus linearis (Goeze, 1777): MSU-ARC, PSUC:ENTO
Lyctus opaculus LeConte, 1866: Hubbard and Schwarz (1878), MSU-ARC
The following four species were reported from Michigan, but we consider them to be adventive, misidentifications or other errors:
Sinoxylon anale Lesne, 1879: Fisher (1950); a port interception, presumed not established
Heterobostrychus hamatipennis (Lesne, 1895): BugGuide; Detroit July 2012 "in a false ceiling", det. from photo by Robert Beiriger; BugGuide: "native to so. Asia, introduced from India into NC and then FL; established in se. FL"
Dinoderus (Dinoderus ) minutus (Fabricius, 1775): Ruesink and Parsons (2021), MSU-ARC; tropical cosmopolitan - adventive in bamboo, presumed not established
Stephanopachys amplus (Casey, 1898): Borowski (2020); presumably listed in error. This is an Arizona sp. apparently known only from the type (Fisher 1950).
