Tramea calverti (Odonata: Libellulidae): New for Michigan with Notes on Other New Reports for the Great Lakes Region

Abstract

Beginning in late summer 2010, the Neotropical dragonfly Tramea calverti Muttkowski, striped saddlebags, was observed in a major northward movement in eastern North America. This species appeared for the first time in three Great Lakes states and Canada (Ontario). A specimen from Michigan is the first and only voucher in the Great Lakes, and an observation in Minnesota established a new northernmost report for North America.
