In this region, there are 25 recorded incidents of the creatures eating birds. The most prolific of these insects is the Chinese mantis ( Tenodera sinensis), which has been introduced to the American Northeast.

The mantises have a particularly gruesome way of eating their prey: head-first. Altogether, 12 different species of mantises have been seen eating 24 types of birds, with hummingbirds as the most common prey. A study published in The Wilson Journal of Ornithology in 2017 compiled 147 cases in which the insects have eaten birds, in 13 countries on six continents. Including birds.īelieve it or not, praying mantises have been officially recorded eating birds in every continent except Antarctica. However, these insects eat many other animals as well. In some cases, male praying mantises actually comprise a significant portion-if not a majority–of a female’s diet during breeding season.

Bird Brains ![]() So while the male would probably be better off to live and mate with multiple females, at least it seems his nutrients give his DNA an elevated chance of getting passed on to the next generation. They also appear to lay twice as many eggs after cannibalizing a male than they normally would. Interestingly, getting eaten may not be as bad as it sounds.Ī study published in 2016 found that when female Chinese mantises consume their mates, they acquire important amino acids that are then incorporated into the eggs they lay. In fact, of the species that exhibit cannibalism of their mates, studies have shown that the females make a meal out of the males between just 13 and 28 percent of the time. and then devours his corpse for nourishment. During mating, the female bites off his head. But if you're a male praying mantis, it can literally eat you alive. “Maybe if the female is starving or if the male irritates her, she might engage in that behavior. “First of all, not all praying mantis species cannibalize their mates,” says Brannoch. However, the frequency of such violence may be just a tad overstated. Praying mantis courtship can be a dangerous affair females have been well-documented biting off the heads and eating other body parts of the males that they mate with. Mantis MatesĪnd sometimes those interests intersect-brutally. Now, as the days shorten in the Northern Hemisphere, they have only two things on their mind: food and sex. The animals have also spent all summer hunting and growing, repeatedly shedding their exoskeletons as they reach lengths of up to half a foot. ![]() “Right now, they’d be looking for mates, so the males might be a little bit more active, more prone to flying around,” says Brannoch, who is also a doctoral student at Case Western Reserve University. It’s not that the praying mantises of the America are more abundant in late summer and fall, says Sydney Brannoch, a mantis expert at the Cleveland Museum of Natural History. Despite their saw-like arms and alien eyes, they pose no threat-unless of course you happen to be an insect, gecko, or hummingbird. If you find yourself outside this time of year, you might come across one of the world's more intriguing insects: praying mantises. ![]()
