DAVE DAVIES, host:
This is FRESH AIR. I'm Dave Davies, filling in for Terry Gross.
If you don't find ants interesting, you might change your mind after spending a little time with our guest, Mark Moffett. In his new book, you'll learn that ant colonies developed coordinated labor forces and cultivated their own food millions of years before we did.
Today, Moffett writes, ants are Earth's most ubiquitous creatures. They number in the millions of billions, and globally, they weigh as much as all human beings.
But trust me, there's even better stuff to come. Mark Moffett is an explorer, biologist and photographer who's traveled the world studying many creatures, but the complex societies of ants hold a special fascination for him. He's studied ants so closely, he's been called the Jane Goodall of the ant world.
Mark Moffett spent two years as curator of ants at Harvard's Museum of Comparative Zoology. He's now a research associate at the Smithsonian Institution. He's written two previous books. His latest, which includes some amazing close-up photographs, is called "Adventures Among Ants: A Global Safari with a Cast of Trillions." I spoke to Mark Moffett in June of last year.
Well, Mark Moffett, welcome to FRESH AIR. Your book tells us about so many diverse and fascinating species of ants across the world, and I thought maybe you'd just give us a taste by telling us about the bulldog ant of Australia, which actually I've read a piece of yours about - and I don't think it's in the book, but it's such an amazing story.
Mr. MARK MOFFETT (Research Associate, Smithsonian Institution; Author, "Adventures Among Ants: A Global Safari with a Cast of Trillions"): Well, Dave, the bulldog ant is one of the contenders for the world's most vicious ant, and in the book, I focus more on the Paraponera, which is a South American equivalent.
Both these species are large, nearly an inch long, built like tanks. The bulldog is interesting because it has very good vision. So if you're in Australia, and you look down, and you see an ant look up at you and turn and follow you and then start running after you, you should probably leave.
DAVIES: So, I mean, can it actually catch up with you and then, what, leap on to your leg?
Mr. MOFFETT: Yes, they're actually good jumpers, Dave, that's right. And there's some contention about which of these two ants has the worst sting. I really wouldn't want to be in the competition, but there are certain people who make a kind of sport in determining the most pain in the different ants.
DAVIES: First some general questions about ants. You refer to them throughout the book, and when you're talking about an individual ant, as she. Why?
Mr. MOFFETT: Well, ants are a sisterhood. They guys really don't do too much. They're kind of kicked out of the society pretty soon after they're born. They have a single function, that is to have sex - okay, two functions, to have sex and die. And they don't participate in the social life.
DAVIES: Right, when you see a swarm of ants, I mean, how many of them will be male and female?
Mr. MOFFETT: They're all female, Dave, that's the thing, no males among them. If you saw a male ant, it would look like a wasp, and it would probably be flying around, and you wouldn't recognize it at all as an ant. Ants are a group of females without males doing a thing.
DAVIES: Okay, I don't know if this varies a lot from species to species, but they clearly are social animals. They work together on so many things. How do they communicate with one another?
Mr. MOFFETT: Well, ants communicate mostly through chemistry. That's the advantage of being small. Scent can travel fairly rapidly, compared to humans, over distances that can lead to the ants signaling large groups, particularly ants who move in dense swarms, like army ants or the marauder ant.
And they sometimes use sound. For example, if you step on a nest, everyone is getting crunched down below, and there's all kinds of cave-ins, and the ants that are buried signal with a little squeak that they need to be dug up.
DAVIES: Wow. But typically, it's by releasing chemicals that they can, what, smell, detect some way?
Mr. MOFFETT: That's what their little antennae are doing. As they wave them around, they are constantly surveying for the scents being released by other ants, and those indicate all kinds of things. They can indicate there's a war going on, that there's food, that the queen needs assistance. They fundamentally indicate nationality.
Ants are very nationalistic, much more than people. They live in societies that are tightly bounded. You cannot defect from an ant colony. And so every ant needs to know whether you're friend or foe, immediately - and they do that through scent, as well.
DAVIES: So if a swarm of ants is out, and one of them sees food and says hey, let's all go get this caterpillar, or another one says here's an enemy we need to prepare to fight, or another one says something else, there are different chemicals within their bodies that will simply release, and the other animals will be prompted to act?
Mr. MOFFETT: That's right, and the thing is that ants being social, in large groups and this is the thing that's unique between ants and humans, you can have colonies of ants up to millions, the size of a city-state - they actually have chain reactions that can lead to mass actions that are very intelligent so that even though a single ant may know nothing of what's going on, as a group, the whole response leads them to go to the best food at the best places. It's this mass reaction that makes ants smart.
DAVIES: All right, well, let's talk about marauder ants. I mean, this is a species, I believe, that you gave the common name to, right?
Mr. MOFFETT: Yes.
DAVIES: Where do you find them?
Mr. MOFFETT: The marauder ant lives in Southeast Asia and India, and I'd seen it in the Harvard collections when I was a graduate student, looking for something cool to do. And the really neat thing I found about them is that the specimens in these drawers of dried ants were extraordinary.
There were all these different sizes and shapes of the workers, and in ants, you divide up the labor often by making different kinds of workers. You know, you can tell a lawyer from a doctor by what they wear and so forth. Ants, you can actually see in their body forms and the toughness of the exoskeletons and other features, and their sizes, what they do.
And these ants have a huge array of sizes. So I knew they had to have fantastic social lives.
DAVIES: Right, and so we have these ants that are of the same species but come in many different sizes, I mean, some several times as large as the minor workers, right?
Mr. MOFFETT: Yes. In fact, the size range of these ants is 500-fold, from tiny little minor workers up to the big majors, or soldiers, if you will.
DAVIES: Okay, so these live in colonies of, what, millions or hundreds of thousands?
Mr. MOFFETT: In their case, hundreds of thousands, and almost all of them are the minor workers. There are a variety of intermediate sizes. The soldiers are rather rare. The minor workers, the little ones, are the workhorses that do most of the drudgery of the colony. The bigger ones do more specialized tasks.
So the largest ones, for example, often serve as school buses, moving bunches of small ones to the battlefields, where they catch prey.
DAVIES: So they climb on to the big ant and just catch a ride?
Mr. MOFFETT: That's right. Energetically, it makes more sense for them all to ride on a big one than to all walk separately. So it's a very sensible ant solution.
DAVIES: Conserves energy for the colony as a whole.
Mr. MOFFETT: Yes, ants are green.
DAVIES: All right, even though they're brown.
(Soundbite of laughter)
Mr. MOFFETT: Exactly.
DAVIES: All right. Now you have a fascinating description of how these marauder ants forage and attack in swarms. Would you just kind of describe that and give us the roles of the different kinds of ants?
Mr. MOFFETT: Well, marauder ants move forward in a swarm. There a couple ways you can organize an attack in the ant world. One is to send out scouts and figure out what's going on in different directions and then have the scout come all the way back, and you get a whole bunch of soldiers going out to do a deed.
But that takes a lot of time. There's this big delay. And so if you have something fantastically important that has to be dealt with immediately, like say a giant prey, like a frog, it's going to probably have hopped off.
Now, the marauder ants get around that by moving their swarm forward blindly, and they depend on shock and awe. So they may not find much because they don't know where they're going. They don't know if there's going to be a frog ahead, but if they find a frog, it's overwhelmed instantly.
DAVIES: Right, they catch little insects, right, but things as big as frogs and geckos, right? Now, how could these tiny ants overwhelm a frog, who I would figure would see this coming and hop to safety.
Mr. MOFFETT: Well, the army ants, which do much the same thing as the marauder ants, they can catch lizards, snakes. They can even kill infants in cribs and cattle, if they're tied up. So their capacity for destruction is immense. That's why you do not tie up your cattle in Africa.
But in all these cases, it depends on a immediate presence of a huge force, and you pour on - well, it turns out the front lines of these raids have these little minor workers, which are the cheap labor, and this is the way the Romans conducted their attacks.
You see in all these movies, the Mel Gibson guy running out ahead, being really macho. No, no, no, he's way back behind there. What they had up front, the Romans, were all these farmers, untrained, carrying their sticks and getting slaughtered. And this is what happens with the marauder ants.
The minor workers, the little guys - or gals I should say - run ahead, get cut in half, left and right in some cases, and then - but eventually, they pin down these large prey because there are just so many of them. And at that point, the raid has moved ahead, and now the bigger guys - gals again - arrive, and they can do the kill without any danger to themselves.
You don't want to put your really expensive equipment where it can get hurt. It's a rule of military warfare throughout history.
DAVIES: So you might have a centipede, for example, and these minor ants will go charging in, relentlessly tearing at the legs of the centipede with no regard to the fact that they themselves are going to get chewed up in the process, and enough of them immobilize the creature, and then the big ones come along for the kill. How do they kill it?
Mr. MOFFETT: Well, a single blow to the head can be enough if you're a very large, major worker, and incidentally, the small ones are about three millimeters long or just over a tenth of an inch, and the large ones are maybe a quarter-inch long.
So they have very powerful mandibles. Much of their mass is the muscles for their jaws. They often don't actually kill the prey, though. They will chop off its legs and carry it back, and I once took a cricket from the ants that was being carried to the nest, and I put it in a little dish, and I looked at it the next day, and it was still alive. It just didn't have any legs or anything. They'd removed all its moving parts.
So I had this nightmare the next night of having all my legs removed and being dragged into the underground chambers of the ant to be eaten at their convenience.
DAVIES: What a nightmare.
(Soundbite of laughter)
DAVIES: Now, do you think the ants deliberately leave the prey alive as they transport it back to the nest?
Mr. MOFFETT: Well, deliberately is, of course, a loaded term. Ants don't have much in the way of thought processes that way, but it's a logical thing for them to have developed as a strategy because in the tropics, where they live, food goes bad quickly, and they're catching a lot of prey, and they may not be able to eat it right away.
And so having it alive there means that they can hold on to it. It can be part of their pantry for a few days.
DAVIES: We're speaking with Mark Moffett. His book is called "Adventures Among Ants: A Global Safari with a Cast of Trillions." We'll talk more after a short break. This is FRESH AIR.
(Soundbite of music)
DAVIES: If you're just joining us, our guest is Mark Moffett. He is an award-winning naturalist and photographer. He has studied ants across the world. He has a remarkable book with descriptions and amazing pictures of ants. It's called "Adventures Among Ants."
All right, now, a lot of what you do is first-hand observation of ants in their natural setting. How do you protect yourself from stings?
Mr. MOFFETT: Well, I don't. I don't take them personally. I believe they're a sign of affection. I obviously have certain relationship problems, but...
(Soundbite of laughter)
Mr. MOFFETT: Well, there's a cost to any relationship, human or otherwise, and if you're going to fall in love with anything, whether it's a human or an animal, you have to take the good with the bad. And stings for me are part of the process, and I have a great tolerance for them.
People find this curious, watching me down with ants, of course, trying desperately to get me away, but I don't - I'm not easily dissuaded.
DAVIES: We've been talking about these marauder ants that you studied in Asia, which live in colonies of hundreds of thousands and, you know, forage and swarm and kill little creatures and bring them back to their nests.
One of the other fascinating things is that these tiny worker ants spend a lot of time in effect building infrastructure for the colony. What do they build?
Mr. MOFFETT: Well, ants who live in small groups, like a dozen or two or something like a hundred, gather a group of people, they don't need infrastructure. They don't need roads. They don't really need to build houses or anything. They can have temporary shelters.
And marauder ants are an instance of a large ant society, where infrastructure is required. And in their case, they're building nests, of course, with lots of chambers, as you might expect, but they're particularly fond of building what are called trunk trails, which are a kind of a superhighway. And those can extend for about a hundred yards, which is a lot of ant miles.
DAVIES: And so what does an ant superhighway look like? Is it simply leveling out the land? Are there overpasses or shelters on it?
Mr. MOFFETT: Well, there can actually be overpasses. It's a complex structure, really. They build a complete cover over it. They flatten it out perfectly. All the different ant sizes get involved. The very largest workers, the ones that I mentioned serve as school buses, will actually push off twigs that fall on the trail, much like elephants will push off logs on trails in India.
And so they serve as heavy-duty road equipment. Other ants gnaw away the surface, make it smooth. The whole point of that exercise is to get the goods and services moving quickly, from colony to the field and back.
And they actually form highway rules along these highways, as well. And the ants coming down the middle of the road are inbound, and the outbound ants go down the edges. So they actually organize things slightly differently than humans do, but still, everything has to be coordinated to get all these foods back and all the information out to the field, where the ants are patrolling and doing their duties.
DAVIES: Now, of course, we're talking again about how the remarkable level of cooperation among ants, I mean, how intensely social these creatures are. And I was amazed to read that the older, weaker ants readily take on the crappiest, riskiest jobs in the colony, right?
Mr. MOFFETT: Yes, well, I said ants are nationalistic, and this is part of the deal. Ants are quite willing to die for their colony. So what they want to do for their colony is much more than we'd want to do for our society, usually, and that includes killing themselves in warfare, including if you come along; and it also includes, if you're dying of old age, they do not have health insurance. They don't argue about such things. They wander off and die if they're diseased or hurt, or they serve what final duties they can, and that includes, as you say, guarding the trail.
So along the borders of the trail are all these old ants, crippled ants, staggering and unable to stand up but yet reaching up with their jaws, feebly trying to keep the enemy at bay.
DAVIES: An enemy like what? An ant from another colony?
Mr. MOFFETT: An ant from another colony or you. It depends who comes first. They'll gladly do themselves in for whatever causes arises.
DAVIES: But they know when they're old and infirm to take on those tasks. How do they know all this? Is anybody in charge?
Mr. MOFFETT: Well, that's the great thing about ant societies, actually, is that nobody is in charge. And it sounds unlikely to us, but it's actually a really good idea.
Terrorism doesn't stop an ant colony. If you come along and smash a quarter of the population, you can never slow the colony down. It has to grow back, but you can never get a nerve center.
Ants disperse all this information amongst themselves, and they move efficiently and do the right thing without anyone telling them what to do.
DAVIES: There's a description in the book of when you decided you needed to see the nest of the marauder ants and had to excavate it. Just describe that process for us.
Mr. MOFFETT: Well, Dave, you'll probably want to come along on my next excavation because it's really kind of fun.
What you do is you get an axe, and you sort of slam it into the top of a marauder ant nest, and apparently, they don't like that because they start pouring out in a mass.
And the important thing to remember, which I've learned over repeated experiences, is to tuck my socks over my pants and make sure my shirt is tucked down and that I'm wearing long sleeves because they swarm up you as you're digging away, and eventually they reach your neck. And at that point, you run like the dickens and start scraping them off your body, and then you come back, and you start digging again.
The goal of this exercise is to see how the nest is organized. It's also to get the queen. She's, you know, the holy grail for ant biologists, and the queen is deep down in the nest.
As I say, ants don't have a leader. She produces the young. She's their mother. She doesn't give any orders, but she holds the colony together through, you know, the relationship as a family.
DAVIES: You write about a lot of different fascinating kinds of ants in the book, ants that live in the canopies of forests hundreds of feet above the ground. And there are some animals that are actually farmers of a kind. Tell us about them.
Mr. MOFFETT: Well, ants are one of the few creatures, other than humans of course, that have invented agriculture. And they've done it surprisingly, it turns out, pretty much exactly how humans did it. They domesticated a crop. They eat a fungus. And these are the leaf-cutter ants, which you've all seen in films and different places, I'm sure, and they carry those leaves along. They don't actually eat leaves.
What they do is they chop them up and make them into a mulch to raise their fungus gardens, and they started doing this quite a long time ago. And the origins of this agriculture is amazing because they - basically ants for a long time didn't domesticate their fungus.
And there are species of these related to the leaf-cutter ants around like this and they have basically a wild fungus that they can snatch and grow at home, and that fungus might return to the wild, and that fungus is genetically diverse and very robust and doesn't get diseases.
And then that went on for about 30 million years or more until the leaf-cutter ants emerged among them, and those ants actually domesticated their fungus. They turned those fungus into a form that cannot return to nature. Like apple trees, these fungi have little bulbs at the tip that the ants eat.
And at that point the fungus was stuck with the ant and vice versa, and they became like one thing. And they bred this fungus so thoroughly and their colonies grew enormously that they have these huge monocultures now that are over-bred, have no genetic diversity and are subject to all these diseases. So the ants, the modern ants, the leaf-cutter ants, have the same problems in agriculture that humans have today.
DAVIES: And do they spend a lot of time tending their fungus fields?
Mr. MOFFETT: The amazing thing is they do virtually everything the human farmer does. They have to clean their fungus, weed them, cull them. They fertilize the fungus. They have to apply pesticides. They invented pesticides. All...
DAVIES: Pesticides? What's an ant pesticide?
Mr. MOFFETT: Well, they grow a couple different kinds of fungi - many of them are on their bodies - of a kind related to the fungus that produces penicillin in humans. And that actually destroys certain diseases that the crop fungus, their food fungus, can get, and keeps those gardens healthy.
DAVIES: Mark Moffett, recorded in June of last year. His book is called "Adventures Among Ants: A Global Safari With a Cast of Trillions." He'll be back in the second half of the show. I'm Dave Davies, and this is FRESH AIR.
(Soundbite of music)
DAVIES: This is FRESH AIR. Im Dave Davies filling in for Terry Gross.
We're listening to my interview recorded last year with biologist, writer and photographer, Mark Moffett, who spent years studying the complex societies of ants around the world. His latest book is called "Adventures Among Ants: A Global Safari with a Cast of Trillions."
DAVIES: You also write about the driver ant and its peculiar bite. Tell us about that.
Mr. MOFFETT: Well, the driver ant come in two forms. The African ones, they're perhaps worse in some ways, because they have jaws like knives and so they can cut human flesh. And so I have actually been with pigmies in the Congo, and gone to their traps, and found antelopes that were eaten alive by a driver ant.
The army ants in South America can't cut. They can pierce though. And they have long, piercing mandibles that are shaped just like fishhooks with a re-curve tip a little knife blade edged to the fishhook. You've seen those if you look closely enough on an actual fishhook. And they - those jaws serve as fishhooks and they actually pierce deep into the skin and at the same time they sting you at the other end. And this is a kamikaze behavior because like a fishhook, they can't remove the jaws once they've done this. They're stuck with you, and the only way to remove them, it's a specialized skill that I've gained, is to get out that Swiss Army knife with those little scissors and chop off the jaws and then tweezer each of the jaws out.
DAVIES: In the book of "Amazing Stories" I was even more amazed as you recount the tale of the Argentine ants and the scale of their colonies in California. Tell us about those.
Mr. MOFFETT: Turns out that only ants and humans have full-scale impersonal warfare, where masses of individuals go after each other. And that's because ants and humans have larger societies than anything else, up to millions of individuals.
And the Argentine ants, having the largest societies, have the most amazing warfare of all. Unfortunately, they're an invasive species and they've escaped Argentina and they're now in California. They have been there for about a century expanding their realm.
But what's been recently discovered is that there are in fact different colonies there. It was thought that they didn't fight until someone accidentally took some of them, mixed them up with what turned out to be a different society and they started killing each other. And these societies turned out to be enormous. There are four of them in all of California. The large of the four is called the very large colony and it extends from San Francisco down to the Mexican border and contains maybe hundreds of billions to a trillion individuals.
This is a single nationality with a single scent. So you can carry an individual ant from San Francisco with you all the way down to Mexico, if you're so inclined, and drop it off and it will merge seamlessly with the society there. You carry that same ant a quarter inch across the border to the next society in Escondido and its dead within a minute. And these huge colonies have borders that are miles long, and millions of ants are dying each month right in people's backyards out of view at the base of the grasses. And it's basically the largest battle ever waged. And it doesn't seem like much because, heck, what are they doing?
But in fact these ants are extremely aggressive, not only to each other but to every other kind of ant. They're wiping out all the native ant species and those ants were important for dispersing seeds and in keeping the soil healthy and having other functions. So California is in the middle of a real ant crisis.
DAVIES: You said millions of ants are dying on a monthly basis. And these are these places, these border scrimmages where huge ant colonies come in to contact. You actually witnessed a battle line, didn't you once?
Mr. MOFFETT: Yes. I went with a friend of mine, David Holway, who's studying this in University of California in San Diego, and he took me to the exact spot where the two of the ant colonies come together, which took a long time to find. They actually had to carry ants from neighborhood to neighborhood and drop them off and see if they were killed until they narrowed down the borderlands. And there you have a line of ants, but dead bodies with the ants on top.
What they do, the live ants on top of this mass, is circle each other, grab on and start pulling, and ants start pulling from a different side and suddenly a leg will pop off or an antennae. They literally spread eagle and tear each other to pieces slowly over time. And this is non-negotiable. No ant says I will not die for my society. So the ants sort of flow into these borderlands constantly and renew the battlefield.
DAVIES: And then retreat when they're beaten and the line is moved a few yards, huh?
Mr. MOFFETT: Well, they're never retreating. The line might move but that's only because there is a greater population pushing the border forward. So these borders do shift back and forth, but there's never a retreat. There is some advantage to moving swiftly, so the ants that attack first and ask questions later, essentially, those colonies tend to overwhelm the other colonies. But none of these colonies have lost yet. This will take the long haul of time to happen because these battles have been going on probably for most of the century that this species has been in California. And that's the amazing thing about these colonies, they're basically - they never end.
And they will just keep going, and in fact they're expanding around the world right now. The same colonies are taking over places like Northern New Zealand. There's a single colony that occupies a thousand kilometers of coastline in Europe. South Africa has a huge colony, and so forth.
DAVIES: Now, there is one other real bad girl out there in the ant world, the fire ants. Tell us about that.
Mr. MOFFETT: Well, the fire ant, of course, is in the American South. The cool story about the fire ant is that it's virtually the same story as the Argentine ant. Because these two species and a number of other invasive species that are causing immense damage around the world all came from the same spot in northern Argentina - a river valley where they have learned to fight against each other with such precision, they cannot be stopped.
DAVIES: And how do they skip over oceans?
Mr. MOFFETT: Well, these ants live in a flood plain where the waters go up and down and they're driven up the trees all the time. And they have to learn very quickly to run to any place that's available to live in. So if a boat pulls up, they're up the gangplank in, you know, no time and heading to New Orleans with a load of coffee.
DAVIES: When I left Texas in 1975 and moved north, there were no fire ants. And my relatives soon told me, when I went back down there, you don't just lie around on the grass. These guys can really hurt.
Mr. MOFFETT: Yes. They're, in fact, worse than the Argentine ants in that respect because they have stingers. And, of course, that's a horrifying experience to everyone in the South now. We know they've been in a battle with the Argentine ant down there. The Argentine ant actually entered the South before the fire ant. The Argentine ant came in through New Orleans. The fire ant came in through a different port, and both of them expanded their ranges ever since.
DAVIES: Can humans fight them? Has that happened?
Mr. MOFFETT: Well, it seems to me the only hope is to deal with the fact that they're such nationalists, that they depend on these scents absolutely to know who's friend and foe. So if we could crack that code, we have the best chance.
DAVIES: The descriptions and the pictures in this book are fascinating, but at some level they're, they're scary. I mean, you know, you look at an ant with these kind of lifeless dots on her heads that are eyes and, you know, you see her using her mandibles to tear apart some hapless insect that's encountered the colony, and you just see this relentless drive for self-preservation, which is expressed in these millions of ants being heartless, relentless killers, which is maybe, you know, the norm in the natural world. But it's very unsettling. I mean do you ever just get creeped out by all this?
Mr. MOFFETT: Creeped out. Well, you know, there can be - I would not like to have been in the war in Vietnam. I think I could get creeped out by human behavior just as much. And this is the thing, that these commonalities between the two of us are actually really important to me. Ants didn't come about any of these things through intelligence. We have choices that we can make through intelligence but we've still made a lot of wrong choices. But they, you know, they do have a total devotion to their societies that is actually almost like a form of love.
They don't have facial expressions like you are pointing out. They have these mask-like faces. That's true of all insects. And it turns out that humans actually judge emotion and character through facial expressions. A person who has lost the capacity to mood their face can get misjudged all the time. And ants because of that don't get a fair shake. I think there's some pretty good emotions going on there.
When I'm chasing an ant through the jungle brush down on the forest floor and I see it through my camera, I see it start to turn. I see the antennae quiver and its body tense because it knows I'm there and it's turning and it's going to respond. And I back up and I hide behind a twig, just as an elephant photographer would hide behind a tree and my emotional connection with the ant is just like it would be to a person or a dog.
And whether that's an accurate representation of the mental condition going on in the ant, I don't know, but there's the same kind of beauty and elegance and positive things going on in ant societies and those things also fascinate me about ants.
DAVIES: Well, Mark Moffett, it's been an adventure. Thanks so much.
Mr. MOFFETT: With great pleasure, Dave. Thanks.
