Tibicen pronotalis (FEMALE)
This cicada is a bit discolored (loss of some greens), but given the options in your region, the best bet is T. pronotalis.

I compared the cicada in your pic's with a series of specimens from the Mid-West. Based on the given size, color, and pattern, this insect is consistent with "The Great Harvestfly".

Additionally, your cicada lacks the "well developed smoky Z" towards the wing tips, characteristic of related species but "lacking" in T. pronotalis.

NOTE: T. pronotalis can be variable in both color and pattern, but the insect pictured here is pretty typical of specimens from the upper Miss. R. - i.e. w. Illinois and Iowa.

Thanks for the ID
Thanks for the ID! I thought I'd ruled out Tibicen pronotalis, because the pictures I found of that species didn't look the same. But the ones you posted look almost exactly like it.

 
Glad to be of help.
T. pronotalis can be variable.....
These cicadas range in color from bright green and red to straw yellow-tan and red-brown, or any combination. The pronotum may also be heavily patterned in some individulas.

The best "key trait" I know, is to look for the smoky "Z" pattern towards the tip of the wings. In pronotalis (and dealbatus) it is faint to absent, but quite dark and evident in all other eastern species.
