“A moth is such a simple machine in the animal world - the go-kart to the modern car - and it takes a lot of glitches to prevent it going. It's this intriguing simplicity, the idea that you could pull it into its constituent parts and put it back together in the same rainy day, that if you pulled back the skin, you could watch the inner workings, that makes a moth such an absorbing creature to study. Moths have a universal character: there are no individuals. Each reacts to a precise condition or stimulus in a predictable and replicable way. They are pre-programmed robots, unable to learn from experience. For instance, we know they will allways react to a smell, a pheromone or a particular spectrum of light in the same way. I can mimic the scent of a flower so that a moth will direct itself towards that scent ...”

“Once you decide on the best poison for the termination, you must work out the correct concentration. For instance, I know that five milligrams of cetratranic acid dropped into a bell-jar with a single moth will take about three seconds to stun it. I know that seven milligrams will anaesthetize it and ten is enough to kill it, providing the moth does not weight more than 3.5 grams. I also know that to kill fifty moths you need five times the concentration or volume of killing fluid, but to kill seven thousand you'd need only two hundred times the concentration. I know that potassium chloride could never kill a larger moth and potassium sulphide would only ever be strong enough to anaesthetize it. I know that cyanide kills anything. But what I don't know right now is the precise amount I will need to kill Vivien.”

“Clive convinced himself that it wouldn’t be long before we’d be able to predict all their [the moths] equations of cause and effect, then perhaps even map out each and every cell, and configure them in their entirety as robots, in terms of molecules, chemicals and electrical signals. And what fed this particular obsession was Pupal Soup. If you cut through a cocoon in mid-winter, a thick creamy liquid will spill out and nothing more. What goes into that cocoon in autumn is a caterpillar and what comes out in spring is entirely different—a moth, complete with papery wings, hair like legs and antennae. Yet this same creature spends winter as a gray-green liquid, a primordial soup. The miraculous meltdown of an animal into a case of fluid chemicals and its exquisite re-generation into a different animal, like a stupendous jigsaw, was a feat that, far from putting off, fed Clive’s obsession. He believed it made his lifetime ambition easier because, however complex it might be, it was, after all, only a jigsaw, and to Clive, that meant it was possible. For all the chemicals required to make a moth were right there in front of his eyes, in the pupal soup.”

“I feel like the caterpillar that we think is making a choice when he eats or pupates but, in fact, is not. He's ruled by molecular forms of incluence acting on the base components of a moth. Likewise, perhaps I have become a killer through circumstances acting on my biological make-up. Which means, of course, that none of this is my fault and that it's all out of my hands.”

“I hated the idea of such a glorious creature beating itself to death in pursuit of something it could never have. It was, after all, just a light. The moth had no idea why it wanted it, only that it did.I paused at the window. “You’re just like them you know. You want the light so bad because you think it’s wonderful, and power-ful, and the answer to all of your little moth dreams, but in reality it is just a deadly desire. No matter what you do, no matter how bad you want it, you can never have it. Don’t you see? The light will bring you nothing but death.”Slowly, I opened my hand again. “Now, go, live your life. Find another moth and make little moth babies, and stop chasing light fixtures,” I instructed, raising my hand toward the stars. Once again, the moth watched me, then fluttered its wings and took off. This time, it flew away, disappearing into the dark. I leaned my head against the window frame, watching, think-ing, wondering if the little critter would ever find happiness. It didn’t take long to get an answer. There, on the other side of the parking lot, was the moth, buzzing wildly against a street light. I began to cry. “I know how you feel, little one,” I sobbed. “No matter what happens, no matter how wrong it is, my heart wants what it wants. I’m just like you, and they are my light.”

“I love her and hate her at the same time. I even love the parts of her that I hate, her vitality and her colour, her disruption and disorder, her humour and her despair, her conceit and her narcissism, her everything that isn't me.”

“You're a little tall to play Ariel." said Moth."And you have way too many muscles," said Mustardseed."But you might be able to pull it off," Cobweb said, "if you can look really constipated.”
