Wow, that's beautiful! I might have to move there one day. Judging from the habitat and my own personal experience with ground mantids, I don't know if they are around there, it may be too humid or cool (unless it gets hotter than the pictures suggest (it being right by a lake and all).
Great find on the Euro female, hopefully she's been mated if she's not too fresh. And another prime example of them being in weird places. As far as the ground mantids go, I just collect around 13 yesterday. I'm sending a pair to Rick for the expo and the rest I'm going to try and breed. Once I get the next generation, I'll be selling them off and you'll be one of the first to get some, assuming you don't come across any by then.
