Interview with Catherine Chalmers from American Cockroach

Excerpts from a Conversation
from American Cockroach (Aperture 2004)

Insects are a window into the unimaginable. Their biology and behaviors are routinely bizarre and enigmatic to us – they are refreshingly outside the human perspective. I think that our experience can be enhanced by an attempt to understand and give meaning to other life forms. Yet, is it possible that a human-centric viewpoint is setting the stage for an impoverished environment?

* * *


Where nature and culture collide is a nexus of fear and confusion. With my previous book, Food Chain, I wanted to explore a basic process of the natural world – killing and eating, being eaten alive – away from which we have endeavored to civilize ourselves. The carnage in Food Chain was deeply disturbing to many viewers. Although I spent much of my time on the project providing meticulous care for the animals I worked with, many viewers blamed me when they saw, for example, images of a snake eating a baby mouse – as if I had killed the mouse. I was fascinated by the strange disconnect between what people seem to want to believe happens in nature and what actually does happen. The snake, of course, needs to eat, regardless of our opinions.

* * *


With American Cockroach, I am interested not so much in troublesome behavior as in an animal humans find problematic. The roach, and the disgust we feel for it, make for a rich conduit to the psychological landscape that inculcates our complex and often violent relationship with the animal world. I can think of few species that are as thoroughly loathed as the cockroach. But interestingly enough, although they carry this heavy burden of our hostility, they don’t do very much in terms of behavior. They don’t eat in a dramatic way, and they certainly don’t have the wild sex life of, say, the praying mantis. They don’t sting, bite, or carry the dangerous pathogens that flies, mice, and mosquitoes regularly do. Having a cockroach in your kitchen is not like having a venomous snake living in the house. There’s nothing about the animal that is life-threatening. The dichotomy of the roach being a loaded subject, yet in habit, a fairly blank canvas, allowed me to bring more to this work.

* * *


It’s likely that there are a multitude of factors that fuel our feelings about cockroaches. They’re nocturnal, coming out at night when we are asleep and vulnerable. They also operate in numbers, whereas we see ourselves as individuals. If we find ten in the kitchen, we know there are hundreds more behind the walls that we can neither see nor get at – a hidden enemy is horrifying to us. And by mutating quickly they can genetically outwit the technologies we throw at them. I also wonder if we have an atavistic memory of when mammals were a diminutive species ruled by the dinosaur. Are we skittish about being dominated again? Who knows? Cockroaches outnumber us, we can’t control them, and they don’t share our values.

* * *


It has never been my intention, though, to offer them an apology, to say we shouldn’t hate or shouldn’t kill them. I’m not advocating for their conservation or their destruction. What interests me is that the degree to which people hate cockroaches is so disproportionate to the actual potential for threat in the actions of the animal. This schism is indicative of the subjectivity – perhaps arbitrariness – with which we respond to nature in general. The cockroach is like a distorting mirror that amplifies the attitudes we harbor.

* * *


One of the things I discovered when reading up on the American cockroach is that they are no longer found in the wild. They have existed for hundreds of millions of years, have survived several mass extinctions, yet we have succeeded in changing how they life. Our homes are now their natural habitat. They are, in a sense, our alter-egos, the shadows that clandestinely follow in our wake. As humans dispersed from Africa, where roaches too are believed to have come from (Linneaus misnamed them Periplaneta americana), they have accompanied us through our colonization of the planet.

I have a theory that early Homo sapiens living in caves probably did not find the cockroach as abominable as we do now; certainly they had more dangerous animals to fear. Our hatred of the roach has perhaps grown in proportion to the boundaries we have erected between ourselves and the natural world. These animals are one of the few remaining species that can cross over at will and challenge those barriers. I think, at a fundamental level, their trespass upsets our confidence in our ability to successfully control and transform nature to suit our needs and desires.

* * *


The distance humans have forged between ourselves and nature is creating villains out of species that were originally seen as benign, and increasingly transmogrifies animals into one of two categories: pets or pests. And, of course, the animals that fall outside these sets are rapidly becoming extinct. Our expanding lifestyle decreases the number of animals on which we spend millions to save, and conversely gives rise to the so-called “weed species,” the animals on which we spend millions to exterminate. It’s a portentous conundrum. People persevere in feeding their need for contact with nature, but what satisfies that longing is increasingly notional. Our culture surrounds itself with natural forms; patterns of flora and fauna abound on walls, sheets, and clothes, but we remove ourselves from the real things in their normal environments. I think we have become a species that prefers the substitute.

* * *


What are the aesthetics of human empathy toward animals? What if cockroaches were red with black spots like a ladybug, or green like a plant, or, iridescent like a dragonfly? Or perhaps came in a variety of colors and patterns, like cats? People seem to prefer soft and fuzzy to hard and shiny, big eyes to thin antennae, feathers to scales, colorful creatures to dull ones. These are choices based on abstract visual qualities, often independent of the animal’s behavior. And I think these preferences have had a formative role in determining our attitudes toward specific species, and even entire classes of creatures. They have played a part in defining what we find to be “good nature” as opposed to “bad nature.” Unfortunately for the roach, it embodies several of our least-favored aesthetic attributes.

I found that once I got past the dark, twitchy exterior, the roach is remarkably subtle and beautiful. Its wings are a glowing, translucent amber, its lithe legs are accented with randomly-drawn spikes, and its antennae explore the world with the grace of a ballerina’s arms. I was surprised to be allured by its shape – its body parts are formally compelling, and this is what led me to expand this project into drawings and sculpture. From there, the roach’s syncopated, rhythmic gait led me to video.

* * *


People prefer to see insects in a garden, pollinating flowers and being useful. That’s idealized nature. But of course, most insects are predators, savagely ripping apart fellow insects, or, in the case of the cockroach, acting as scavengers, recycling waste and debris. Humans don’t like scavengers. And that the American cockroach can successfully scavenge off of us is the worst of insults. We have worked tirelessly to coerce nature to match our vision, but would the world really be a better place if all insects were pretty and only did nice things?

* * *


I sometimes paint or add spines or feathers to the shells of my roaches. These embellishments are superficial and fall off in a few days, leaving the roach unharmed. But the act of transforming the animal brings up an interesting characteristic of human behavior. We specifically set out to shape the planet as if it is a tabula rasa for our desires. The terror of whatever a roach does to us pales in comparison to what we can do to it. Genetic engineering is opening up new possibilities for designer plants and animals. Pretty soon, “glowfish” will be available – goldfish engineered to fluoresce, created just for our entertainment. If roaches are here to stay, might we take an alternate route and begin pest manipulation instead of pest extermination? Engineer them to look like a favorite insect, or mammal, or perhaps the kitchen wallpaper? There is real power and bite behind our aesthetic choices. We have been practicing this craft for millennia, such as carving a wolf into a toy poodle, but now we have more tools in our box.

* * *


Death ties us to the roach in a unique way. We kill them – they survive. We kill ourselves – they survive. I wanted this body of work, though, to get away from the discussion of specific deaths. So my executions were reenacted with already-dead bugs. I have been raising roaches for years and consequently collecting the dead for years; their corpses animate this part of the project. The “Execution” series is not about the suffering humans have endured at the hands of humans, but what other species have endured at the hands of humans. I do not want, in any way, to diminish the pain and horror that we have experienced through the centuries with these methods of killing. It is the opposite perspective: not looking in but looking out across the animal barrier that I am endeavoring to explore through this work.

* * *


We have difficulty looking something in the eye as it dies – even if we really want it dead. Not so other predators. For example, the dog; the more its squeaky toy squeals, mimicking a suffering prey, the more excited the dog gets. Humans are incredibly efficient killers, yet remarkably queasy at facing or acknowledging what we do. For us, there is a disjuncture between mass, anonymous, silent deaths, and those that have been individualized. We do not feel the same emotion and responsibility for what we do not witness, whether it is a behind-the-wall pesticide death, or the graver problem of wildlife loss from habitat destruction. But, for the animal facing extermination or extinction, what meaning are our distinctions?

* * *


We are at a time in history when we are becoming aware of the larger impact we have on other species. The roach, strangely enough, is emblematic of the questions we face as we struggle to decipher our relationship to the animal world in general. What do we love, what do we kill, what do we save, and what becomes extinct? We have been drawing lines in the sand forever, but maybe now is a good time to re-imagine what’s on the other side.

Interview with Catherine Chalmers from Food Chain

Interview with Catherine Chalmers
by Michael L. Sand
from Food Chain (Aperture 2000)

MICHAEL L. SAND: Your photographic work with animals started with flies. Why flies?

CATHERINE CHALMERS: I was interested in working with an animal that lives a parallel life in our own home. And I was interested in the fact that flies are so easily dismissed. You dust them off your windowsill or you chase after them with a fly swatter. That is the extent of most people’s interaction.

I wanted to try to see what they are like, to see how they conduct their lives. What they do when they’re hanging out. How they socialize. And, interestingly, over the four months that I observed and photographed them, I never saw them fight. They don’t seem to be territorial.

MLS: It appears they engage in group sex, but not fights.

CC: Oh yeah. When a female was receptive she was inundated by four or five flies trying to mount her at once. And she would mate with many of them in a row. Other than that, they’d congregate, hang out, loiter.

MLS: Did they make a lot of noise?

CC: They’d buzz, but they weren’t as loud as my crickets. And to my surprise the flies didn’t smell. Just the sweet smell of their food, powdered milk and sugar.

MLS: Where did you get the flies?

CC: I ordered pupae cases from a biological supplier, which is the easiest form in which to deal with them, as opposed to eggs or maggots. You can pour them into a terrarium, and in a couple of days they hatch. The population curved about every six weeks, which is roughly their life span. You see, they were not breeding as fast as they were dying of old age, because I kept the bottom of their cage too clean. I was hesitant, or obvious reasons, to let their cage become disgusting enough for a real populations explosion.

MLS: And this work led directly into “Food Chain?”

CC: It did, because I saw the flies do so many great things, and I understood the importance of paying attention to the animals we classify as “lower life forms.” I noticed, though, that with the flies I had missed two essential aspects of life – eating and dying. The flies ate and died at the bottom of the cage, and I photographed them up in the air, so as a result I missed those two things. And, as I repeated to myself “eating and dying,” the two ideas got coupled together and I thought of eating and dying at the same time, which is basically one animal eating another while it’s still alive, and that lead to “Food Chain.”

At first I was horrified by the idea of raising an animal to feed to another animal. It disturbed me that I was going to be governing life in that way. But when you think of how central food chains are to all systems in life, it makes a certain amount of sense. So, even though I was uncomfortable with the idea, and maybe because I was uneasy, I felt it was an important area to explore. Western society has become divorced from the act of killing the animals we eat. I wanted to see why.

MLS: How did it evolve from there? Did you know right away what animals you wanted to raise, what would be practical and what would be interesting?

CC: There were a number of problems. One – who eats whom? I’m not a zoologist; I don’t even have a garden. So I didn’t know how to piece it together. And the second problem was, what can you raise in the confines of a loft in New York City? A friend who is an entomologist at the American Museum of Natural History gave me a list of suppliers of live insects. So I started collecting catalogues, which were mostly for scientists. Some were agricultural, and they talked about which insects ate which pests.

I thought of a number of different scenarios for starting the food chain, until I saw the tobacco hornworm larva in the Carolina Biological catalog. I liked it because it was turquoise, and it wasn’t poisonous, and it would eat tomatoes, which are readily available. After finding the bottom of the chain the rest fell into place. I knew I wanted to use a praying mantis, but I thought that it would be the top predator. When I found out that a tarantula would eat a praying mantis, the praying mantis slipped to the middle position and the tarantula became the top dog.

MLS: And did things go as planned?

CC: Not at all. Everything was out of whack. The caterpillars grew up, pupated, and turned into moths. The praying mantis egg cased hadn’t even hatched. And the tarantula wasn’t eating because it was about to molt. I went through two more life cycles of the caterpillars into moths, into caterpillars, into moths. I took six months to get the timing right.

It took a mini-ecosystem to raise praying mantises. You need fruit flies to feed them when they’re babies, then houseflies, then crickets as they grow bigger. The stage when they’re eating houseflies is the hardest. It takes hours to feed the whole brood, which are housed individually because they’re cannibalistic. I had to capture one fly at a time from a big cage and transfer it to each praying mantis. I got so good at catching flies that I could even capture the ones flying free in my loft.

The first praying mantis I put on the set with a caterpillar was, to my horror, attacked by the caterpillar. I had put so much time into raising each praying mantis that the possibility of a caterpillar killing it was very upsetting. I quickly realized how subjective our ideas about death are. We so often root for the underdog, but when your underdog is abundant and bites, you think differently. I broke the two apart and waited another month for the praying mantis to mature.

Then, when I put the tarantula up on the set with the praying mantis, nothing happened. It’s hard to know when a tarantula is hungry, and the one I was using was slow, docile, and wasn’t hungry very often. The problem was that the praying mantises were getting big and would soon reach a size that might make the predator-prey scenario reverse itself. I had only one spider and didn’t particularly want to lose it.

So I thought I’d better get a more reputable top predator. I hadn’t spent six months of daily work raising praying mantises to have the project fall apart because of a finicky eater. So I got a frog. I put the frog on the set with a praying mantis, and boom, in two shots it was over. First you see a hungry frog facing the mantis, and then you see just a leg sticking out of the frog’s mouth. (See front and back of book jacket.)

But, I kept trying with the tarantula because my entomologist friend said the spider would enjoy the praying mantis, and needed a varied diet anyway. One time in the middle of the night, while I was watching Silence of the Lambs (which coincidentally used the same caterpillars), the tarantula ate the praying mantis. I stayed up the rest of the night taking pictures as it ate.

MLS: You went to the trouble of raising more praying mantises to photograph them having sex. You knew, I assume, of the legendary aspect of the praying mantis – that the female might devour the male?

CC: Yes, but after many months of raising mantises I realized I didn’t know a male from a female. I found an obscure pamphlet published in England thirty years ago by a couple whose hobby was raising praying mantises. To determine the boys from the girls you do the obvious: look under their skirts. You lift up the wings and count the segments on their abdomens. Males have eight and females six. After the last molt, you wait three weeks, heat the male up to 80 degrees, and put them together in a big space. They also said that if the female was well fed, she was less likely to eat him. But, it’s not just a matter of male as meal. When she bites his head off she gets more sperm, according to one study I read.

The male was very cautious approaching the female. The female, for the most part, ignored him. He did most of the courtship. I thought of insects as having instantaneous sex. I stood there, camera ready, thinking it would be over in a flash. But not so with the praying mantis. They can stay coupled for hours. All my males got away unscathed, except one. After hours of being joined together she reached around, grabbed him by the neck and bit his face off. It took her another couple of hours to eat almost every last bit of him.

MLS: Why did you decide to use a plain white backdrop for these photographs?

CC: I had just photographed the houseflies in black and white. Flies don’t have the same relationship to gravity that we do – up, down, sideways, they are comfortable in positions we are not. So flies floating free in an unspecified white space felt appropriate. It also took them out of the dirty world we associate with them, and out of our world too. While I was thinking about doing “Food Chain,” I knew I wanted a similar sort of feeling. I wanted the situation to be neutral so you could see the animals and what they were doing.

MLS: It certainly focused attention on them. It removes all distraction, and it also dissolves the borders that exist between humans and animals in a natural environment.

CC: I didn’t even consider putting them in a natural setting. The tomato is not on a vine, the praying mantis is not on a bush, and so forth. But, had I done this, the pictures might look like nature photography, which I think sometimes accentuates the distance between them – the animals living out there in the wild – and us, living inside our protective walls. I was interested in removing that distance. I wanted to interrupt the relative comfort of “they’re there and we’re here.”

“Food Chain” is, after all, only a simulation of what goes on in the natural world. In actuality, the four animals originally come from very different places and would never have met if it weren’t for human intervention.

It used to be that humans were more exposed to the processes of nature. But, besides seeing animals on TV and in zoos, our interaction with them has whittled down to domesticates, like dogs and cats, and scavengers, like roaches and rats. In order to experience a chain of life I had to re-create it myself.

MLS: Isolating these creatures in a pristine white space also plays with scale in an interesting way. These animals appear so much bigger than they are in real life.

CC: To be taken seriously, size helps. If insects were the size of dinosaurs our relationship to them would be vastly different. Creatures smaller than our feet tend to be stepped on. If you take a newborn mouse that’s an inch long and you make it twenty inches, it looks like it could be the fetus of many species. Even human.

MLS: The newborn mice do look like fetuses. They exude defenselessness, don’t they?

CC: It’s as if they shouldn’t be born yet. They are completely defenseless, yet they, of any animal, could certainly use some weapons. They are the mainstay of so many diets. Frogs eat them, snakes eat them, birds eat them, spiders eat them, cats eat them. I call them “nature’s Cheerios.”

MLS: Caterpillars seem vulnerable like that too.

CC: Caterpillars have more defenses, though. They bite and many are poisonous. Baby mice can only squeal. Tobacco hornworm larva, the species I used, have a horn off the back, leading a predator to attack the tail end. Then the caterpillar loops around and bites the attacker. Certain caterpillars that live in the rain forest make a noise, which attracts ants. They call the ants to live with them to protect them from wasps; in exchange the ants get sustenance from the caterpillar’s body.

MLS: Which also challenges the idea that it’s every creature, or every species, out for itself. Do you ever think about why the pinkies are so defenseless? Why they’re “nature’s Cheerios?”

CC: Where to start with the question of why? The fact that mice can have so many babies over a lifetime answers the problem of so few surviving.

MLS: Does the mother value them less? Does she feel less of a need to protect them than other parents do?

CC: No, I think she values them like other mammals do. Although sometimes she’ll eat one, usually the first one out. The females seem to like having babies to tend, and when they don’t, they’ll kidnap another mother’s babies. Then the mother steals them back, and this can go back and forth for quite a while. When several mothers have babies at the same time, they’ll pile them all together.

MLS: Why do they pile them?

CC: The babies like to be next to each other for warmth and protection. They huddle together, and if a few get separated, the mother puts them back together.

MLS: Does it ever get violent?

CC: The only real violence, horrible horrible butchery, is with males.

MLS: Males on males?

CC: Yes, brothers that get along, come of age, and turn on one another. They have to be separated. The most stable situation is several females and only one full-grown male. One time, though, a male butchered all the babies. Not just killed them, but dismembered them and threw the body parts around the cage. It was very upsetting. But, you know, after that, I thought, if they can mutilate their own, I don’t feel so bad feeding a few to my snake.

MLS: Have you had any problems with animal-rights activists?

CC: Working with animals can elicit extreme and often opposite reactions. I try to provide my animals with a healthy life, and I never personally harm a thing. But my snake, frog, and tarantula are not vegetarians. Sprouts and tofu don’t appeal to them. Either they die of starvation or else a cricket, mouse, or worm dies to feed them. That’s the basics of nature – there’s no way around it. During an interview I did on National Public Radio, for Ira Glass’s “This American Life,” the interviewer wanted to record me working. At the time I was photographing “Pinkies,” so I put Pumpkin, my baby corn snake, on the set and gave it lunch – a baby mouse. The mouse squealed while it was being constructed and the show included it. Ira said he got several calls from animal-rights activists complaining about a mouse dying on a radio show.

MLS: I guess it’s not surprising that it was the mouse that people had trouble with, as opposed to a caterpillar, for instance.

CC: Sure. It’s completely subjective. Caterpillars are insects and we seem to have the least amount of affection for them. But if insects were wiped off the face of the planet – and fortunately the billions we spend on insecticides haven’t succeeded – our days would be numbered.

In the case of the caterpillar and the praying mantis, the caterpillar’s point of view is, “Hey, you know, I want to live to be a moth. Don’t eat me.” And the praying mantis says, “Look, I’m hungry.” These are two opposite positions. Then we come along with our own opinion. Praying mantises have big eyes, more personality, and a head that moves on a neck, as ours does. Caterpillars have scant expression, are plentiful, and eat our crops. So we root for the praying mantis. But, in general, the animals we like and actively try to protect are much less abundant than the animals we work hard to eliminate. The way we live radically increases the very species we hate the most, the so-called weed species, the things that live off of us.

MLS: It also applies to our judgment about what we should and shouldn’t eat, doesn’t it?

CC: True, but even when we don’t eat meat, we’re still displacing ecosystems by clearing land and planting crops. So even if you’re eating corn, something’s dying for you to eat that corn. The animals that lived on that land for starters, and then all the ones who try to eat that corn instead of us. There’s really no innocence in eating, no matter how you chase it around.

MLS: Were there times when the animals did not behave in a way that you anticipated?

CC: I was surprised how easily the predator-prey relationship could be reversed. I didn’t want to set up a situation that would be against what might happen in nature. So I built a big, open set, and if the animals didn’t want to be there, they could leave. And some did.

I was also amazed at how many times my frogs lunged and missed their prey.

MLS: There is that sequence in which a large praying mantis faces off with a small toad.

CC: One of my full-grown, female praying mantises was dying of a wound inflicted by a male when they were mating. Of course, it is the female who is supposed to attack the male.

She was clearly on her last legs so I decided to feed her to my little garbage can of a toad that ate everything in sight, no matter how big. He went for her immediately. He kept her in his mouth but couldn’t swallow her, then spat her out. Then sat on her head. And then turned and hopped away.

MLS: You have photographed the skin left behind when a praying mantis molts – which you call a “ghost.”

CC: They molted many, many times before reaching adulthood, at which point they got their wings became sexually active. After that they didn’t molt again.

When molting they hung upside down, and slid out the top of their skin. It was a critical time and the enclosure had to be kept moist. The praying mantis came out looking fragile and transparent and the skin looked like a perfect clone. I collected these and had an army of ghosts, kind of like China’s terra-cotta warriors.

Many of the animals I raised were invertebrates, meaning they wear their skeleton. When my tarantula molted she flipped on her back, looking rather dead, and slowly slithered out of her furry body. When she came out, she looked like a brand new spider. She was so beautiful and the colors were very vibrant.

MLS: Imagine if we could molt!

CC: All those plastic surgeons would be out of business. And many orthopedics too. If the spider breaks or even loses a leg, she can regenerate it the next molt. But it is also a very vulnerable time and many animals die in the process, either by being tangled in their skin or by being attacked. They are defenseless while molting.

A couple of my praying mantises emerged twisted and horribly deformed. One somehow got its arms crossed in the process. It died because it could no longer catch or eat its food.

MLS: What was the hardest part of this whole project for you to deal with?

CC: The hardest part was the very heart of the project: seeing a living thing being eaten alive, and choosing the animal to have that fate.

Specifically, I had a hard time feeding full-grown mice to my rapidly growing snake. They knew what was going on, they saw the snake coming, and they were scared.

After a while, though, I realized that the real problem with the mice was not so much the horror we have of a mammal being eaten by a reptile, or the burden of choosing who lives and who dies, but overpopulation. I had huge population explosions. Even though I had seven predators, my mouse community was still increasing exponentially.

MLS: Which is a problem in the natural world too. I suppose.

CC: Thankfully there are predators.

MLS: How did you decide where “Food Chain” would end?

CC: Three stages is enough to get the idea across. I also wanted to stay with the smaller creatures. My interests are with the animals that make the world go round but get little attention.

MLS: The frog eating a baby mouse was very unexpected, almost uncanny, to me. We don’t tend to imagine that frogs eat mice.

CC: There are many reasons that it seems improbable. Snakes are associated with evil, while we tend to think of frogs as cute. But some frogs are poisonous and quite nasty. We imagine frogs eating insects, or fish, and we don’t have a problem with that. In reality, frogs will eat all sorts of baby animals too.

MLS: You photographed some of the survivors from your work with pinkies.

CC: The photographs in “Pinkies” mask the reality of what happened to the baby mice. It looks like all the babies were eaten. But, of course, the opposite is the case. Ninety-nine percent survived. I had an arrangement with the pet store; they took my weaned babies and in exchange I’d get more mouse food. They were happy because they sold my mice for twice the regular amount, since they were fancy, with multi-colored coats.

I decided to photograph the multitude of survivors and put them on the set for a group portrait. What chaos that was. They were running all over the place. I took some individual shots too. In the scope of it all, mice are doing just fine out in the world. They’re not in danger of becoming extinct.

They’re not losing the struggle.
