Mayflies return to Michigan, signaling summer's arrival

The return of mayflies marks the onset of summer in Michigan, with these insects covering cars and buildings near Lake Erie and Lake St. Clair. David Lowenstein from Michigan State University explains that while mayflies emerge in large numbers, serving as a crucial food source for fish and birds, they can overwhelm residents living near water. Their presence indicates a healthy aquatic environment, and residents can expect to see more as summer progresses.
