Using an ear-like organ in the center of their chest, they can hear sound above 20, hertz, just outside the range of human hearing. If they detect the series of chirps that bats use to make their final approach toward a bit of prey, they can change their flight path, dropping into a downward spiral that helps them avoid being caught, Brannoch explains. Besides this talent for hearing, these animals have incredible eyes.
Unlike all other insects, they can see in three dimensions. And yet, their 3D vision works completely differently from our own, says Vivek Nityananda , an animal behavior expert at Newcastle University upon Tyne in north England. In a study published earlier this year, Nityananda and his colleagues fitted praying mantises with tiny 3-D goggles, not unlike the ones humans wear to the movies.
The differently colored lenses allowed the researchers to show the insects two images at once and then record their reaction. This allows humans to judge depth. After all, it could be lunch. But mantises, which only possess about one million neurons—compared to that billion or so found in the human brain—have figured out a way to do it more efficiently.
Another oddity about mantis eyes: It appears that they have pupils, and can follow you with their eyes as you move. But this is a bit more complicated than it seems. Meanwhile, the light receptors all around the dark spot are reflecting certain wavelengths, which is why the rest of the eye appears green, white, brown, or purple. Therefore, the mantises pupil is actually a bit of an optical illusion. No wonder scientists call it a pseudopupil. And thus, they cannot focus their eyes on one point in the same way that animals with pupils can.

Mantis Mates And sometimes those interests intersect—brutally. Share Tweet Email. So while a praying mantis will eventually die after laying eggs, the cause of death is falling temperatures in the fall, rather than the act of actually laying the eggs.
Praying mantis do have a number of predators in the wild. This can affect when praying mantis die. It is interesting to note that each praying mantis egg case ootheca can contain dozens, or even hundreds, or tiny baby mantids. Only a tiny fraction of these will end up reaching maturity. The rest die on the way, and one major impact is that of other predators.
Baby praying mantis can fall foul of spiders, birds, small mammals and even larger mantis. If the baby mantis survives these difficult early weeks then it will moult a number of times, growing in size, and becoming more able to defend itself.
Even then, however, a large praying mantis can make a juicy meal for any predator capable of finding them and picking them off. Praying mantis parasites have not been studied extensively, but there is evidence of parasitism in praying mantis.
One common example are the parasites known to affect praying mantis eggs. Some parasitic wasps will inject their own eggs into the oothecae, with the wasp larvae rapidly hatching and feeding on the developing praying mantis. This also affects when some praying mantis die, as some perfectly fertile eggs may perish during incubation thanks to the impact of parasites.
