Mantis cannibalism by Dr Beetle
Mantis cannibalism by Dr Beetle: "Refreshingly, a study by Liske and Davis in 1987 threw the first human light on the importance of the natural environment to behavior in mantises. The Chinese mantis Tenodera aridifolia sinensis was among those wrongly accused of sexual cannibalism during mating in several previous studies. However Liske and Davis, although still stuck in the laboratory, made some concessions to the mantis. They fed the mantises regularly, turned the bright observer lights down, and left the room to replace a fidgeting human observer with a stationary video camera. Surprise surprise, no cannibalism occurred! In fact, a whole courtship behavior by the male and female mantises, new to science, was observed!"
