Praying Mantis Romance

Here's some nature. Claudius found Sylvia in her usual spot and well, these 4 pictures say enough.

They stayed like this for hours. As far as I can tell Claudius left Sylvia unscathed. I thought she might eat him but google sources tell me usually that does not happen. I also figured out that these are probably Chinese Praying Mantises.

I will be looking for an egg sack, also called an ootheca. Hopefully Sylvia will lay it close by.
