Is it appropriate to be finding goodness in ecological systems? Many people say ‘no, absolutely not’. ‘We can’t look to nature for guidance in human values’, they say. ‘We are humans, nature is different.’
I had a colleague once who was very keen on this point. He was utterly convinced of his basic view that we cannot and must not try to derive values from nature. His clinching argument was the praying mantis. The reason: because after sex the female kills and eats the male. His shudder was thoroughly genuine!
Well, I have to agree that this is not a good model for human life. From a biological point of view, though, it tells us something interesting about mantises. There are over 2,000 mantis species (Mantodea) on Earth, and in all of them the female lays her eggs and then walks away and leaves them. There is no nurturing of the young. She puts all her effort into building up her strength so that she can lay lots of healthy eggs. And given that a female can lay up to 200 eggs, a lot of food has to pass through that little body.
Females can eat, for example, sixteen crickets per day, and in addition to their preferred insect food, they are known to eat mice, frogs, birds and newts. In the time of egg-formation, the female has two main needs: to develop her own strength and to attract a partner to fertilise the eggs. Once that is all in place, death is the next step: lay the eggs, walk away, die and be done with it! After eggs and sex both partners are expendable.
There is no way humans could live like this even if we wanted to. Our young require years of care. It is true that a child can be raised without a father, but it is equally true that it takes a community to raise a child. We are not alone in requiring social co-operation to raise the young. Many mammals do likewise, and so too do many birds. None of us creatures who care for and socialise our young for long periods of time would be wise to take lessons from mantises.
The meaningful division in this context is not between humans and ‘nature’ but between high levels of care and low levels of care of offspring. Both strategies are viable, but they are in no way interchangeable. Scientists refer to them as the r and K selection strategies. One involves large parental investment and few offspring (K), the other involves large numbers of offspring and little parental investment (r).
The r/K difference positions humans as a ‘K’ type of creature; we are like some creature and unlike others.
To return to the joy of sex mantis-style, recent evidence offers a more complex and therefore more interesting story. For a start, it turns out that female mantises only eat their sexual partners if they are hungry. The experiments that showed cannibalistic females ripping into their mates used mantises that were starving. Research outside the lab in fields and gardens did not discover strong evidence for cannibalism.
Males want to copulate every bit as fiercely as females want to lay strong eggs. If there is to be a new generation, the female needs both nourishment and sex. It is rather a happy adaptation that males can, if necessary, provide both. They actually can continue their sexual activity, and may even copulate more rapidly, when their head has been bitten off!
Most creatures are choosy about who they mate with, and mantises are no exception. Females put out a pheromone to announce that they are ready for males, and then it is up to the guys. Male mantises do approach females cautiously. Scientists describe courtship rituals for some species in which the male comes toward the female waving his antennae and wiggling his abdomen. The two of them stroke each other and then mate, perhaps for up to six hours. However, other species take a fly-in-fly-out approach, with the male arriving, having sex, and departing as rapidly as possible.
Out in the garden mantises are doing what mantises do, but inside a high-powered research institute a scientist shudders at the thought of ruthless and predatory females. The insect femme fatale is a prevalent gender stereotype, and apparently a fearsome one. In her human form, she is a beautiful ball-breaker, intent on destroying men while taking all she can from them. Thanks to feminist analysis we now understand that such gender stereotypes are part of patriarchal power. They rationalise control over women, excluding us from full humanity, and they embed the imagery in the realm of nature where it can seem to be incontrovertible.
There is always a fine balance between prejudice and humour. Character types and popular imagery are a significant part of our cultural lives, and a lot of them can be quite funny. I’m rather taken with the kinds of lessons we could share based on male mantis behaviour. Most of us will be aware of the fly-in-fly-out type, of course, and who could fail to recognise the brainless guy who would go on fucking even if his head did fall off!
We learn a lot about humans by examining the stories we tell about nonhumans.
Surprisingly, though, there is actually a lot of positive mantis lore in the human world. In a completely different frame of reference, a northern Chinese style of martial arts known as Tang Lang models itself on mantises. It recognises that mantises are fierce little predators. They are swift and precise, shift from immobility to action instantaneously and take their prey completely by surprise. According to Wikipedia, ‘One of the most distinctive features’ of Tang Lang ‘is the “praying mantis hook”: a hook made of one to three fingers directing force in a whip-like manner. The hook may be used to divert force (blocking), adhere to an opponent’s limb, or attack critical spots (eyes or acupuncture points).’ The basic idea is to work with the principle of overcoming weakness with strength.
So, is there a problem with finding goodness and other blessings in nature? The question goes beyond stereotypes and joking. There is a lot to be learned from the natural world, but learning should not be confused with mindless mimicry. The fact that some females kill their sexual partners is no more a guide to human behaviour than is the fact that some males take an f-i-f-o approach to sex.
The most interesting examples, like Tang Lang, show humans carefully observing and translating other creatures’ knowledge and behaviour into forms that are suited for human life.
Along with martial arts, let us think about translation arts.
When poets translate poems from another language, they have to think about the meaning of the words in the poem and about how to bring that meaning across. At the same time, a poem has sound, rhythm, tone and other characteristics that are part of its power as a spoken form of art. The ‘soundscape’ or ‘music’ is integral to its overall poetic effect. Can a soundscape be brought across from one language to another? Is it better to have a literal translation that closely follows the words but loses the music of the poem? Or should the act of translation try to recreate the music, perhaps changing the poem radically in order to do so?
There are no absolutely right or wrong answers to these questions. Each poem in translation is a unique event. The main point is that translation is itself an art, and thus requires thought, creativity, passion, and strong understanding.
Thinking like a mantis requires far more creativity than simple copying. Interspecies translation is like poetry translation. When humans seek to learn from nature, we need to work like poet-translators and think in terms of art, not imitation.
Think of Earth creatures and systems as poems in languages that are foreign but not entirely incomprehensible. Our task as humans is to translate: to find the meaning and the music, the ways of life and life’s poetry. For we are part of the music of Earth and our capacity to join in harmoniously depends on both the accuracy of our knowledge and the skill of our translations.

There is a highly informative documentary about mantises, and although the narration is astonishingly anthropomorphic it is nevertheless fascinating (view here). It describes itself this way: Published on Aug 26, 2015. Taking a close look at almost hundred days of a Praying Mantis’s life, the movie tries to bring about some incredible images of the creature’s lifestyle, as well as eating and reproducing habits. It covers the whole cycle of laying the eggs, hatching and growth of the insect. This feature changes a lot of theories that have been set about the Mantis.

To see ferocious predators in action, watch Nature’s perfect predators.
Wikipedia has two articles on praying mantis martial arts, northern and southern. The quote is from the article on the northern style. For more detail see the Kung Fu Republic.
The field of translation is huge. I have learned something of the arts of translation from my partner Peter Boyle, a poet who also translates. For analysis of translation issues, a classic text is the 1921 essay by Walter Benjamin in which he worked with the idea that translation is itself an art (read here). Willis Barnstone provides an interesting and accessible overview of poetry translation issues (read here).
There is a fascinating field of biomimicry which finds technological inspiration in the natural world; it is not the focus of this essay.
r/K selection theory has undergone numerous critiques and refinements since it was first posited. It remains a useful tool for drawing broad comparisons.

Fun Fact: Praying Mantises Eat Bird Brains

Poor hummingbirds. The fragile, fleet-winged birds often don’t make it past their first year of life as they are tasty snacks for cats, large-mouth bass, snakes, lizards…you get the idea. Now, perhaps surprisingly, we can add praying mantises to that macabre list.
A new paper reviewing the avian death-literature finds that praying mantises are enthusiastic predators of the tiny birds, and they go about it in gory fashion, often burrowing in through the eye sockets to tear apart the birds’ brains. Included in a press release are a number of pictures, and the results aren’t pretty:

All in all, researchers from the U.S. and Switzerland found 147 cases of mantis-on-hummingbird predation spanning every continent but Antarctica. Twenty-four species of birds and 12 mantis species were accounted for, an indication that the behavior is widespread. Hummingbirds became mantis easy targets after getting caught in bird feeders and plants. Once ensnared, the odds were pretty grim: The researchers note that only two percent of birds managed to escape the insects’ oversized claws, although some 20 percent were freed by humans.

More than 70 percent of the cases were from the U.S., where praying mantises were released decades ago in an attempt to control pests. As enthusiastic predators, mantises are happy to chow down on anything they can get their claws on though, and hummingbirds happen to be squarely in their sights. The results were published last month in the Wilson Journal of Ornithology.
The number of birds killed by mantises still pales in comparison to those killed by cats and man-made objects like wind turbines, however. In fact, the reflective windows in office buildings probably rack up far more bird deaths. Still, the statistics serve as another example of the unintended side effects that result from releasing invasive species into a new environment. It’s also a reminder that nature is quite brutal.
