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.

Dichelonyx linearis (Gyllenhal, 1817): BugGuide, iNaturalist Observations, Ruesink and Parsons (2024), MSU-ARC; In his unpublished thesis Cornell (1972) considered this to be a synonym of D. elongatula as he could not find any consistent differences to separate the two. BugGuide says "Morphological differences between D. linearis and D. elongatulus are not well defined. Brown (1946) species concepts and geographic ranges are followed here where D. linearis occurs inland and D. elongatulus occurs in coastal areas (roughly the Maritimes through to New England)."
