Spring is nature's way of saying, 'Let's party!'
Sexual cannibalism is common among most predatory species of mantises in captivity, and under some circumstances may also be observed in the field. 90% of the predatory species of mantis participate in sexual cannibalism. The female may begin feeding by biting off the male’s head (as they do with regular prey), and if mating has begun, the male’s movements may become even more vigorous in its delivery of sperm. Early researchers thought that because copulatory movement is controlled by a ganglion in the abdomen, not the head, removal of the male’s head was a reproductive strategy by females to enhance fertilisation while obtaining sustenance. Later, this behavior appeared to be an artifact of intrusive laboratory observation. Whether the behavior in the field is natural, or also the result of distractions caused by the human observer, remains controversial.
