Very sleek looking mantis climbed up the screen of my bedroom window, and continued climbing up the wall. About 75mm from head to end of body. I revised my size down to 75mm based on finally getting a ruler and measuring the length of the marks I made until I could find my ruler. 75mm puts it at the top of the size range. I've seen much, much, larger individuals in Santa Clara, CA. Oddly enough, I don't think I ever posted one. I think my reasoning back then was that a 560 pixel image of something that large was just too small to show adequate detail. Now I regret it, because if the same species, it would shatter the 75mm upper limit.

On the other hand, the ones I saw in Europe were closer to the 50-75mm range.
