Cicada color variation?

Hi there! I’ve been collecting some cicadas now that the season is winding down, and they’re getting close to their end of life. I know that M. cassini has an all black abdomen, M. septendecula has thin orange stripes, and M. septendecim has thick orange stripes and is generally larger. However now and then I run into color variations that I have some trouble identifying. Pic below for context, with a typical M. cassini beside for comparison:

To me this seems like an M. cassini with a big orange blot on its side and upper abdomen. Do you agree? Or is something else going on? Are these species capable of crossbreeding?
