Sex isn't worth death?

The current issue of Nature points to evidence that suggests male praying mantises might be more leery of their potential mates than suspected:
[M]ale praying mantises do know they could be eaten after sex, and they don't like the idea. Biologists at New York State University have found that males can assess how hungry females are: if the risk seems high, males approach more cautiously and mount from a greater distance. How exactly they manage the latter isn't clear.
