Then the male, grown old and decrepit, takes counsel with himself, hunts no more, becomes shaky in his walk, creeps down from the lofty heights of the trellised dome and at last collapses on the ground.

The Mantis goes in for battle and cannibalism; the Empusa is peaceable and respects her kind.

To what cause are these profound moral differences due, when the organic structure is the same?
Perhaps to the difference of diet.
