It is a fresh error: for all her warlike aspect, the Empusa is a peaceful creature that hardly repays the trouble of rearing.
Installed under the gauze bell, whether in assemblies of half a dozen or in separate couples, she at no time loses her placidity.

Like the larva, she is very abstemious and contents herself with a Fly or two as her daily ration.
Big eaters are naturally quarrelsome.

The Mantis, bloated with Locusts, soon becomes irritated and shows fight.

The Empusa, with her frugal meals, does not indulge in hostile demonstrations.

There is no strife among neighbours nor any of those sudden unfurlings of the wings so dear to the Mantis when she assumes the spectral attitude and puffs like a startled Adder; never the least inclination for those cannibal banquets whereat the sister who has been worsted in the fight is devoured.
