Ricky B sent us this sound file of a cicada that he recorded in August of 2010 in Chicago:
Cicada MP3 (735 KB file size).
Can you guess which species it is?
Hint: try sites like Insect Singers and Songs of Insects sites for ideas.

Sounds like a loud chorus of Tibicen pruinosa.

However, as far as we know T. winnemanna sounds the same, so without knowledge of either morphology (usually) or geography, you can’t be sure which one it is. Chicago is supposed to be pruinosus.

I agree Dave – went by geography and chose T. pruinosa. I have heatd T winnemanna in North Carolina and it is difficult to tell them apart.
