The Hall of the Singing Caryatids

In a secret brothel for oligarchs, where the main character Lena goes to work, the girls have to play ancient Greek statues of caryatids. To keep them perfectly still, they are given a Mantis-B preparation made from praying mantises. But with it, the girls also receive an unusual side effect—an instinct typical of female praying mantises: to devour the male after mating.
