Nightmarish Nature: Cannibalism
Let’s return to explore more Nightmarish Nature, shall we? This segment focuses on cannibalism, as we generally find it icky / taboo and because it’s more common than you might think. There are many different reasons that different creatures engage in cannibalistic practices. Energy waste doesn’t last long in nature; gaps are filled as things evolve to utilize whatever resources are available to meet their own needs. C’est la vie (light up another cigarette). In any case, the challenge to the cannibal lies in determining kinship and not accidentally erasing their own line or progeny, thus decreasing their likelihood for survival over generations. Oh, and in avoiding those pesky prion diseases…
Resource Driven Cannibalism
Resource driven cannibalism can occur when competition for resources is high. This may be due to scarcity, with individuals taking to eating each other to avoid themselves starving to death (with those consumed either still alive and killed to this end, or eaten after death of other causes). Or it may be outside of the cannibal’s control, considering the spread of Mad Cow Disease from feeding beef meal harboring the prion disease (and parts from other mammals like sheep) to growing cattle to save money, ’cause it’s not like the cows were allowed to order whatever they wanted. Or it may be due to direct conflicts with other groups of the same species, either due to competition for resources, mating rights and/or territory. These behaviors have been noted in mostly male chimpanzees raiding other groups, which have even been documented as all out wars against other males in neighboring bands, campaigning to eradicate all outside of their ranks.
Thinking about chimpanzees, males are also documented to gang up on alpha males seen as too controlling or sadistic, with groups of younger males attacking and rendering the alpha male to pieces, often consuming his flesh and blood in the process. This can upend established hierarchies to replace them with new structures, for example with a new male taking on the role of leader. But cannibalism can also be used to reinforce existing hierarchies, as seen in African Wild Dogs wherein the dominant pair will kill off any offspring that other dogs may have birthed so that the pack will focus on raising only the alpha pair’s pups, thusly reestablishing and enforcing social structure while ensuring the best survival chances for the pups raised by channeling all resources to the one brood.
Infanticide & Filial Cannibalism
Like African Wild Dogs, other parents may also eat their offspring, or better yet their rivals’ offspring. Stillborn or unhealthy offspring may be consumed, or just any that they can get their hands on at birth. (Again with the young male chimpanzees…) Some creatures enter into cycles wherein smaller individuals are more vulnerable to predation by larger ones both within and outside of ones own species, as is seen among many fishes with eggs and smaller fishes playing an important role as prey to larger ones. Other creatures may engage in these practices to reduce competition (for themselves and/or their offspring) and/or increase opportunities to mate. Male cats are notorious for killing kittens that are not their own in order to bring females into heat again sooner, potentially increasing the likelihood of mating with said females themselves while decreasing future competition. Win-win! Female cats must take great care to hide their kittens in order to protect them from males as much as other predators, and can have kittens by different fathers within the same litter in order to increase their kittens’ overall survival as a group with father cats more willing to accept kittens when their own kin are present.
Mantids and spiders are especially known for sexual cannibalism, with larger females consuming males during copulation, but this is not always linked to vast size differences and does not appear in every species. Females who engage in this practice may have healthier eggs in larger clutches, thus increasing the survival likelihood of more of their offspring. Sometimes the risk to the male suitor of being mistaken for another species by an aggressive would-be mate is high, and various rituals have developed within certain species to help avoid such mistakes and entice the female to mate. Male spiders are known engage in elaborate dances, movements, tapping and silk spinning rituals to avoid being eaten pre-copulation or at all. It’s a hell of a lot more involved than a good pick up line and a well-timed drink, as you can see here.

Nightmarish Nature: Worrisome Wasps
This time on Nightmarish Nature we are examining wasps. Wasps are truly terrifying, and not just because some of them sting or are aggressive, though those are often the first ones we think of because we as humans come in conflict with them more directly. No, wasps are extremely varied and some are just outright bizarre… stinging doesn’t even begin to touch on the worst horrors they can inflict.
Now many wasps are actually very helpful to us humans. They act as pollinators and keep pests under control. But if you are another insect, especially a large or fleshy one bulking up, watch out. An encounter with the wrong wasps can mean an untimely and horrible death. A few wasp species will disassemble and eat insects bit by bit but that’s just the start of it, others do even more sinister things.
There are parasitic wasps that will lay their eggs in or on a host insect, like a large beetle, a cicada, a spider or a big juicy caterpillar – there’s pretty much a wasp for everything… A female may sting said insect to subdue it while she acts out her nefarious plans for the next generation (I once watched a spider hanging out in an outdoor potted plant whose fate was sealed, unaware of the horror that awaited it as a female wasp flitted on and around it, stinging and laying eggs before flying off again). Different wasps have different host insects and strategies for this, but the result is pretty much the same. Essentially, when the wasp’s eggs hatch, the larva will eat the creature from the inside out, either saving its vital organs for last or waiting until the time is right.
Caterpillars are especially susceptible to this in all stages of development: egg, caterpillar and pupa. Some species of wasps will lay eggs among caterpillar eggs, others will lay them within the caterpillar eggs, and still others will target the caterpillar itself, or even its pupa. Most build upon the host’s voracious appetite and ability to grow in mass so quickly, waiting until the opportune time to engage in their own frenzy of consumption. Some wasps will even target other wasps that target caterpillars, and this can go like four layers in – it’s like Inception level consumption from within.
And weirder still is the mutualism found between fig trees and very small wasp species. Both are dependent upon one another for their reproductive cycle to be complete. It’s very complicated and I won’t do justice to the cycle trying to explain it, so I recommend that you check it out here on the US Forest Service site.
Anyway to make a long story short, eating figs can even result in eating wasps. Crunch. Crunch. It isn’t actually all that terrifying though; the fig breaks down much of that matter (especially from the original female insect) to use itself as it ripens. And honestly a lot more foods contain insect parts than you may be comfortable with already, they’re pretty much in everything… So that horror aside, the coevolution of figs and wasps that has gotten them to this point is really quite remarkable.
Wasps are truly extraordinary. Many species are super specialized in their life and reproductive cycles. There are over 900 species of fig wasps alone, each dedicated to a different species of fig tree. And the parasitic wasps are also very specialized, with different species targeting different hosts at different stages of their development.
Nightmarish Nature: Freaky Fungus
Now I’m not talking about your aunt’s mushroom pate, I’m talking about mind-controlling tendrils of terror. They aren’t animals, they aren’t plants, they aren’t yummy mushroomy goodness, they aren’t magical (at least not the good kind of magic) and they’re actually kind of terrifying, especially if you’re a bug.
Essentially there are whole subspecies of cordyceps fungus (as well as others) that spread through insect hosts, and no, it’s not like a bad dinner party where your guests just don’t take hints but more a sort of Invasion of the Body Snatchers. Well, more specifically like The Last of Us. Variants of these fungi are very targeted to specific bugs, and certain species of ants, beetles, spiders and even mantids can find themselves afflicted by this. The results aren’t pretty, and it’s also called zombie-ant fungus for good reason.
So the fungus spreads its spores through the air where they comes in contact with new host insects of its selected type and are absorbed into the body. Once they find an appropriate specimen they begin the takeover… An insect affected by the fungus will begin to behave oddly as the fungus signals its brain to act in ways that the fungus needs it to in order to complete its own life cycle. The host will not engage in its normal buggy activities while the fungus drains it of nutrients and prepares it for the next wave of terror. The fungus can even grow tendrils to control muscle movement, puppet-mastering the host’s body.
As the fungus grows and prepares to send forth spores, it sends signals to its host to climb as high as it can, perch atop a plant or blade of grass or whatnot, and clamp down with its jaws in a death grip, to contort itself into a perfect spore-dissemination cannon. The fungus will grow long tendril blooms out of the insect’s body to rain down more terror on new unsuspecting hosts going about their buggy business. If the insect is a social creature (like an ant), it’s nest-mates may also try to drive it as far from their home as possible out of fear of what will soon come to pass. As these spores implant themselves in new host insects, the cycle repeats itself.
Here’s a link to National Geographic, not for the feint of heart. This is enough to strike terror into the heart of every ant, among many other bugs.
So essentially here’s yet another reason to be glad you’re not a bug. Because you don’t want to fall victim to a zombie body snatchers fungus takeover. Frankly, I’d prefer the sneaker-squash to the slow and confusing death that this sort of thing brings.
