Damselflies and Dragonflies of Berrien County, Michigan

The damselflies and dragonflies belong to the Order Odonata, a group of aquatic organisms within the Class Insecta. The primary source used in compiling a list of the damselflies and dragonflies Berrien County was Edward J. Kormondy’s (1958) Catalogue of the Odonata of Michigan (.pdf). This was supplemented by Mark O’Brien’s Odonata known from Michigan, which includes distribution maps prepared 2000-2005 based (in part) on records supplied by participants in the Michigan Odonata Survey since 1996.

These sources produced a combined list of 45 species of odonates (18 damselflies and 27 dragonflies) known from Berrien County, which represent 8 families and 24 genera. O'Brien lists 165 species and 49 genera known from the entire State of Michigan.

In the following list, species attributed to Berrien County by Kormondy are marked with an asterisk (*) while those attributed to the county by O’Brien are marked with a hat (^). Common group names for suborders and families are from the BugGuide, while common species names are from Odonata of Michigan. Habitat descriptions are from Kormondy.
