The praying mantis daily consumes its own weight in food and has become a legend. In ancient times it was worshiped in Greece and the Orient, and even today Japanese gamblers will stage mantis fights.

The voracious mantis is familiar for its forelegs, held like two supplicating hands; its triangular, swivel head; its bulging eyes; and its long, thin body. Smaller than an ant when hatched in the spring, it reaches four inches before succumbing to the cold in the autumn. It lies in wait on leaves or branches, gently swaying to and fro, then quickly grabs its prey with its spiky forelegs. The sharp mandibles dissect the victim, and the meal is digested within fifteen minutes.

There is that gruesome business of cannibalism. The female of the species has the habit of eating the male immediately after mating, if he isn’t fast enough to get away.
