Insect Identification - Black Cicada !enter image description here I came across a black cicada in northwest Missouri last week (May 2015). I am only familiar with brown cicadas. What makes this black one different? Is it a different species, or do the brown cicadas change color at some point in adulthood?

A little digging on wikipedia seems to have answered my question. This picture of a 17 year cicada, Magicicada septendecim is pretty close to what I saw. !enter image description here

Furthermore, this seems to match the time and place, as the Kansas Brood of 17 year cicadas is scheduled to emerge this year and should appear in the Missouri-Kansas area. It also explains why I'm not familiar with these cicadas, 17 years ago I wasn't paying attention to them.
