Cicada species?? - Tibicen pronotalis

Tibicen walkeri, Great Harvestfly

This is the largest and bulkiest cicada in North America. It was formerly called "Tibicen marginalis", but this name is preoccupied by an old-world species.

The only other cicada that is slightly smaller in our fauna is T. auletes, which is without the "golden M" markings on the back.

Thanks!

Thanks for the posts!!! With the info provided I was able to narrow it down to the one you identified (Tibicen Dorsata) or another one Tibicen Auletes. It's been hard to tell from pictures I've found on the web but they look very similar. I appreciate the really quick response too! The curiousity was killing me. Thanks!!!!

Grand Western Cicada?

Given your location, it could be a Grand Western Cicada (Tibicen dorsata), but I'm no expert and can't say for sure.

I agree, it's Tibicen dorsata.

A great picture reference can be found here.

not T. dorsata

Hi, Have to agree with Andy. I've been catching, watching, listening to these critters all my life, and this is not T. dorstata. That species is a richer brown (no green) with stronger black and white markings. The T. pronotalis / dealbata types are usually green or at least greenish, and look very similar, but the dark markings tend to be less strongly developed. You can clearly see greenish coloring on this one.
