I believe this is a Tibicen pronotalis, but am not sure. It was very noisy, in fact, it startled me as I walked past it so much, I jumped. I picked it up and tried to place it on a leaf for a better shot, but it flew off. These are very hard to ID, I've heard, so I'm trying to size it to best of my memory. But, I believe the head was approximately 18mm or so wide, if that helps.

I should wait before I move these to a guide page.
