Williamsonia lintneri (Odonata: Corduliidae) - A first Michigan record with additional notes on W. fletcheri

Abstract

Williamsonia lintneri is newly recorded for Michigan, and additional Michigan sites are given for W. fletcheri. Both species appear to be bog/fen-obligate inhabitants, and adults may appear as early as late April in Michigan. In addition, the North American distributions of both species are summarized.
