Actually, there's research that indicates that mantises don't actually bite off each others' heads during mating in the wild. It might happen, but probably not every time. It's probably an artificially inflated statistic from the lab conditions the mantises in question were kept in. So, yeah, a little less grossness in the world.

And now the little wasps have started to hatch, so I've been taking even more pictures of it, and it's just...it's so gross and yet so interesting, the whole system they have.
