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 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.

Recently raised to family level by Robertson et al. (2015).  Considered by some to be a subfamily (Murmidiinae) within Cerylonidae.


1 genus, 1 species

?Murmidius ovalis (Beck, 1817): Ruppel (1983); only one sp. of this genus in N.A.; is this in the wild or only a stored grain pest in MI?
