Periodical Cicada or a Look Alike?

Today my kitten Toots found this awesome orange Cicada. Since I used to be completely obsessed with bugs I knew enough that the orange Cicadas are the gang that only comes out every 17 years, or is it 7 years? See once I started looking up info on the lovely & informative internet all the facts began to conflict, even to finding that there were possibly 17 year Cicada look alikes. huh? Maybe they got their years off a little, or are ahead of the gestation curve. Is there an entomologist out there who can help me out on this one, would love to know what's up with my new buggie friend! And did ya'll know that people eat these things?!! OH yes they do, here are some Cicada Recipes, like German Chocolate Cicada Cake ,Cicada and Chickpeas, and Cicada Granola Chews (don't worry there's recipes for quiche and something involving mayo too!) But best check it before ya wreck it, cause it's advised that pesticides may be on their bugalicious bodies, so choose your culinary location wisely and don't try them if you have shellfish, nut or soy allergies. I think this means they are gluten free though :)
