Ninety species of Odonata are now verified by specimens for Wayne County, MI, a highly urbanized county in the southeastern corner of the state. This total represents 54% of the total number recorded in the state of Michigan. Thirty-three species not previously reported from Wayne County have been collected since 2000, despite a long history of collecting in the area and relatively little remaining appropriate habitat. These results suggest previous workers may have neglected to do much serious collecting here, and emphasize the need for collecting and monitoring Odonata in urban areas.
