Butterflies of Berrien County, Michigan

The butterflies are a somewhat artificial subgroup of the Order Lepidoptera (butterflies and moths) of the Class Insecta. Lepidopterists have traditionally separated butterflies (Rhopalocera) from moths (Heterocera) based largely on the club-like antennae of butterflies and the feather-like antennae of moths, a practice followed here for simplicity.

The 75 species of butterflies attributed to Berrien County represent 5 families, 15 subfamilies, and 52 genera. In the following list, an asterisk (*) denotes a species documented from the county in Sherman Moore’s (1960) A revised annotated list of the butterflies of Michigan (.pdf), while a hat (^) denotes a species attributed to the county in Butterflies and moths of North America (BMNA). Species validity, taxonomy, and nomenclature were checked against the All-Leps North American checklist:
