The Japanese giant hornet is not the largest insect in the world, but perhaps the most fierce. It can grow to two inches in length, with a wingspan of three…. Here’s how the hornets work: scouts zoom around, searching for honey bee hives. This is all they do, from when they wake in the spring to when they hibernate in the fall. When a scout finds a hive, it leaves pheromone markers around it, which draw other hornets. When the others arrive, they begin systematically slaughtering the bees. A Japanese giant hornet can kill 40 honey bees in an hour. A nest of Japanese giant hornets, around 30 or so, can destroy an entire honey bee colony in a few hours. The hornets seize the bees one by one and literally slice them apart. They cut off their heads and limbs and wings and keep the juicy, most nutrient-rich parts, which they chew into a paste to feed to their larvae. They eat the bees’ honey and devour their young. They do not take over the bees’ hives or carefully consume all they have killed. They take only the flight muscles and other juicy bits and leave the heads and limbs lying around.~~ Complete article available online via WLA Journal
As I read this, I wondered: does an insect even have a brain? Turns out it does, though it might be more accurate to call it a ganglion, a collection of nerve cells, rather than what we think of when we say “brain”.
A team of researchers at Macquarrie University in Australia consisting of a zoologist/neuroethologist and philosopher have hypothesized that an insect “has a capacity for the most basic aspect of consciousness: subjective experience.” That is, insects may experience a mental state, that it “feels like” something to be an insect. Maybe they wonder if these giant meat creatures who keep intruding into their spaces and swat at them have brains.
Crenshaw takes a more behavioral view of insects in this essay. As a lifelong entomophobe, I found it quite creepy to read about all the ways certain insects wage what can only be called war. I was a lot more comfortable with his etymological exploration of the word “hornet” in various constructs: it’s related to buzzing. He attributes Biblical references to hornets to Hebrew words for panic, or army. We’ve been observing insect behavior for a long, long time.
I wonder what it feels like to be the Japanese giant hornet destroying a honey bee colony, or an army ant, fire ant, wasp, or spider, the other insects whose behavior Crenshaw examines before turning to the most panic-inducing, war-waging creature of all.
When Rome fell to the barbarians, while the city was sacked and burned, while a thousand years of darkness set upon the western world, someone, looking at everything they had ever known fall, must have thought that the invaders in all their glorious multitudes looked like swarming ants. When Masada was surrounded, one of the besieged surely believed the Romans were hornets, alien, so far removed from humanity that they were of another world. When the Greeks stood at the narrow neck of Thermopylae, they must have seen the hordes coming for them, wave after wave after wave, as non-sentient, some form of mindless drone. And when the airplanes lit the night skies over Baghdad, a child, huddled in a corner somewhere, certainly believed that some creature from nightmare, from legend or lore or myth, had arisen like prophecy.
I know what it feels like, on this day, to hear the buzzing of hornets.
