The wing length appears short. Based on given info, T. canicularis is the most likely candidate not only by locality, but time of season (mid-September in Michigan). Although T. linnei occurs across the upper mid-West and can persist into late summer, it is usually less abundant that late into the season (*esp. that far inland & at that latitude). In contrast, T. canicularis can still be quite abundant throughout the month of September (17th of Sept) into early October some years.

The position of the wing node, shape of the costal margin and wing length can be tricky and I have been advised to be careful using node position and line bisection tests for definitive id. There are several reasons these diagnostics can fail incl. geographic variability, individual variability, sexual dimorphism and even hybridization.

Moved from Linne's cicada.

This guy just looks a bit more like T. canicularis to me. A series of images - preferably lateral pic's might aid in a more accurate id.

The wing shape is distinctive.
