Sadly it's mine. I don't know who to thank for it, but it's everywhere.Merle looks like you've got a nasty patch of Sericea Lespedeza growing in that picture...hopefully it's your neighbor's
I'll have to measure it the next time I go up. I think I have a red oak that's bigger too. I wanted to pick up that mantis, but was worried she'd eat my hand off.What's the DBH of that oak tree?
That looks like a B&C Mantis to me as well
