The word "mantis" means "Kamakiri" in Japanese. And with another word "praying", it sounds like emphasizing her "life".
The Japanese "Kamakiri" stands for "cut in a sickle". It is really direct.
This is the picture that I took the day before yesterday while walking around a river.
Although it is small one, the female eats the male for the "Egg laying".
She may be praying then...
