Surely you've seen a caterpillar in your lifetime, and you've probably even handled one, but how much do you know about Lepidopteran larvae? These cool facts about caterpillars will give you new respect for what remarkable creatures they are. During the larval stage, the caterpillar must consume enough to sustain itself through its pupal stage and into adulthood. Without proper nutrition, it may not have the energy to complete its metamorphosis. Malnourished caterpillars may reach adulthood but be unable to produce eggs. Caterpillars can eat an enormous amount during a life cycle stage that typically lasts several weeks. Some consume 27,000 times their body weight during their lifetime. The larval stage of the life cycle is all about growth. Within the span of a few weeks, the caterpillar will grow exponentially. Because its cuticle, or skin, is only so pliable, the caterpillar will molt multiple times as it gains size and mass. The stage between molts is called an instar, and most caterpillars go through 5 to 6 instars before pupating. No wonder caterpillars consume so much food! In most cases, when a caterpillar ecloses (hatches) from its egg, it will consume the remainder of the shell. The outer layer of the egg, called the chorion, is rich in protein and provides the new larva with a nutritious start. That's one seriously muscle-bound insect! By comparison, humans have just 650 muscles in a considerably larger body. The caterpillar's head capsule alone consists of 248 individual muscles. About 70 muscles control each body segment. Remarkably, each of the 4,000 muscles is innervated by one or two neurons. On each side of its head, a caterpillar has 6 tiny eyelets, called stemmata, arranged in a semi-circle. One of the 6 eyelets is usually offset a bit and located closer to the antennae. You would think an insect with 12 eyes would have excellent eyesight, but that's not the case. The stemmata serve merely to help the caterpillar differentiate between light and dark. If you watch a caterpillar, you'll notice it sometimes moves its head from side to side. This most likely helps it judge depth and distance as it navigates somewhat blindly. Using modified salivary glands along the sides of their mouth, caterpillars can produce silk as needed. Some caterpillars like gypsy moths disperse by "ballooning" from the treetops on a silken thread. Others such as eastern tent caterpillars or webworms construct silk tents in which they live communally. Bagworms use silk to join dead foliage together into a shelter. Caterpillars also use silk when they pupate, either to suspend a chrysalis or construct a cocoon. There are way more than 6 legs on most caterpillars you've seen, but most of those legs are false legs called prolegs, which help the caterpillar hold onto plant surfaces and allow it to climb. The 3 pairs of legs on the caterpillar's thoracic segments are the true legs, which it will retain into adulthood. A caterpillar may have up to 5 pairs of prolegs on its abdominal segments, usually including a terminal pair on the hind end. Caterpillars with a full complement of prolegs move in a fairly predictable motion. Usually, the caterpillar will first anchor itself using the terminal pair of prolegs and then reach forward with one pair of legs at a time, starting from the hind end. There's more going on than just leg action, though. The caterpillar's blood pressure changes as it moves forward, and its gut, which is basically a cylinder suspended inside its body, advances in sync with the head and rear end. Inchworms and loopers, which have fewer prolegs, move by pulling their hind ends forward in contact with the thorax and then extending their front half. Life at the bottom of the food chain can be tough, so caterpillars employ all kinds of strategies to avoid becoming a bird snack. Some caterpillars, such as the early instars of black swallowtails, look like bird droppings. Certain inchworms in the family Geometridae mimic twigs and bear markings that resemble leaf scars or bark. Other caterpillars use the opposite strategy, making themselves visible with bright colors to advertise their toxicity. A few caterpillars, like the spicebush swallowtail, display large eyespots to deter birds from eating them. If you've ever tried to take a caterpillar from its host plant only to have it fall to the ground, you've observed it using thanatosis to thwart your efforts to collect it. A swallowtail caterpillar can be identified by its smelly osmeterium, a special defensive stink gland just behind the head. Caterpillars and plants co-evolve. Some host plants produce toxic or foul-tasting compounds meant to dissuade herbivores from munching their foliage, but many caterpillars can sequester the toxins in their bodies, effectively using these compounds to protect themselves from predators. The classic example of this is the monarch caterpillar and its host plant, milkweed. The monarch caterpillar ingests glycosides produced by the milkweed plant. These toxins remain within the monarch through adulthood, making the butterfly unpalatable to birds and other predators. It's hard not to be captivated by the fluttery, fragile beauty of butterflies and moths. But the caterpillars they start from — with a variety of colors, shapes, markings, and armor — can be equally captivating. What caterpillars all have in common is the incredible metamorphosis they undergo on their journey from egg to butterfly or moth. Caterpillars represent just one stage of this transformational trek — the larval stage — during which their main purpose is to eat and grow. They grow so much during their brief lives that they typically shed their skin several times, often revamping their appearance from one instar phase to the next. Afterward, butterfly caterpillars molt one final time into a hard chrysalis to begin their magical makeover and moth caterpillars (with a few exceptions) wrap themselves in a silky cocoon. Whether you love identifying caterpillars in the wild or determining friend from foe in your garden, here's a before-and-after look at some of Mother Nature's most notable species. Ryan Hagerty / Wikimedia Commons / Public Domain At first glance, these stunning green caterpillars resemble small snakes or tree frogs — a clever disguise designed to ward off predators. Most extraordinary are the false tan eyespots ringed in black. They're not real eyes, but the level of detail in this mimicry is remarkable, including black pupils in the center complete with white highlights that resemble light reflections. If the "evil eye" fails to scare off predators, spicebush swallowtail caterpillars can break out their bright yellow retractable hornlike organs (called osmeteria) located behind their head, which bear a chemical repellent. These arresting creatures — found throughout the eastern U.S. — hide in folded leaves during the day and venture out in the evening to feed on their foliage of choice, which includes red bay, sassafras, and spicebush. They morph into big, beautiful black-bodied butterflies that sport patches of blue and rows of light spots along their wing edges. Spicebush swallowtail butterfly. John Flannery / Flickr / CC BY-ND 2.0 The hickory horned devil looks menacing, but it’s just a harmless, giant caterpillar. One of the largest caterpillars in North America, hickory horned devils can grow to over five inches in length. Everything about them — from their startling turquoise-green bodies arrayed with black spikes to their prickly orange horns — can invoke fear in the uninitiated. Turns out it's all a ruse. These giants, found in eastern U.S. forests, are about as gentle as they come. After feasting on the leaves of hickory, ash, persimmon, sycamore, and walnut trees, they burrow a few inches into the ground in late summer. (They're one of the few moth caterpillars that don't spin cocoons.) The following summer, they emerge as ravishing orange, gray, and cream-colored regal moths, with an impressive six-inch wingspan.

Once hatched, these strikingly striped orange, black, and white caterpillars devour their nutrient-rich egg shell and begin gorging on milkweed leaves. In the process, they also ingest toxins called cardenolides that don't harm them but are poisonous to predator birds. Within two weeks they've bulked up to 3,000 times their original size. After this food fest, mature caterpillars attach themselves to a leaf or stem, transform into a chrysalis, and emerge a few days later as the familiar orange-, black-, and white-winged beauties that are so beloved. Monarchs are found throughout North, Central, and South America, Australia, Western Europe, and India. Each fall, monarchs embark on a massive migration to their wintering grounds in Mexico and along the California coastline.

The puss caterpillar is one of the most venomous in the U.S. Underneath that toupee-like fur are hidden toxic spines that stick to the skin. Just one touch can unleash excruciating pain far worse than a bee sting. Symptoms may include swelling, headaches, fever, nausea and vomiting, and even shock or respiratory distress. The more mature the caterpillar, the worse the sting. Puss caterpillars eventually become Southern flannel moths with yellow, orange, and creamy fur on their wings, legs, and bodies.

But this dietary preference isn't just about nutrition; it's also about predator protection. Passion flower contains toxic, bitter-tasting psychoactive alkaloids. By munching these plants, zebra longwing caterpillars become foul-tasting and toxic, too — an idea that's visually reinforced via their black spots and long black spines. These imposing creatures are common throughout Central America, Mexico, Florida, and Texas and eventually transform into alluring butterflies known for their long, narrow wings adorned with black and pale yellow stripes.

Judy Gallagher / Flickr / CC BY 2.0 Judy Gallagher / Flickr / CC BY 2.0 It's not hard to see how this caterpillar got its name: It's all in the neon green "saddle" on its back, edged in white with a purplish-brown oval spot in the center. Vibrant colors are yet another way Mother Nature sends a warning. These crazy looking critters, found throughout the eastern U.S., Mexico, and Central America, may only be an inch long, but like puss caterpillars, they pack a walloping sting. Beware their four lobes of poisonous spines — two in front and two in back — as well as several smaller stinging protrusions lining their sides. By comparison, at maturity, the fuzzy, chocolate brown saddleback caterpillar moth is as benign as it looks. Saddleback caterpillar moth.

Decked out with horns on their heads, forked tails, and a series of black spikes along their spines, these ravenous caterpillars spend most of their time gobbling banana leaves and sugar cane. Owl butterflies are known for their love of fermented fruit and the fake owl eyes on their wings (complete with a pupil and iris) that are perfectly fashioned to frighten off predatory birds and lizards.

Pseudopanax / Wikimedia Commons / Public Domain Michael Hodge / Wikimedia Commons / CC BY 2.0 These plump green bruisers, found throughout the U.S. and Canada, grow to be over four inches long. As they pack on weight, they turn from black to bright sea green to iridescent bluish green (like the one pictured here). Most impressive, though, are their many blue, orange, and yellow protuberances (tubercles) wielding black spines. They may look scary, but it's all for show. Cecropia moth caterpillars don't sting or cause harm to humans. Rather, they morph into North America's largest moth and one of its most spectacular species. Adult moths sport reddish-orange bodies and brown wings marked with bands of orange, tan, and white, with white crescent-shaped marks and eye spots. Cecropia moth. Marvin Smith / Wikimedia Commons / CC BY-SA 2.0 Clint Budd / Flickr / CC BY 2.0 These spiky natives of northeastern Australia begin their life on the leaves of a rainforest vine called Aristolochia. Though the vine is poisonous to other caterpillars — and people — Cairns birdwing caterpillars thrive on it. In fact, they store the ingested toxins in the fleshy orange, yellow, and red spines on their backs as a deadly defense against predators. The butterflies they become (Australia's largest) are equally striking, particularly the vibrant, multi-colored males. Cairns birdwing butterfly. Bernard Spragg NZ / Flickr / Public Domain Greg Dwyer / Wikimedia Commons / CC BY-SA 2.5 At first glance, you might mistake the hag moth caterpillar for a hairy spider. More commonly known as a monkey slug caterpillar, this creature is in a realm all its own. It really doesn't resemble any other caterpillar with its flattened hairy brown body, six pairs of curly, tentacle-like legs (three short and three long), and hairy protuberances sprouting from its head. Those hairs sting, causing irritation and an allergic reaction, particularly in sensitive people. This bizarre-looking caterpillar transforms into the decidedly less bizarre and innocuous hag moth with its small hairy body and pale tufts on its legs. Hag moth.
