All About Caterpillars
Caterpillars start out being a little creepy and crawly, but their transformation into a beautiful butterfly or even a moth rivals any makeover program we have today. Let’s take a fascinating journey to explore the world of the caterpillar.
The caterpillar is the larval stage of butterflies and moths. It can be found throughout the world in forests, sandy beaches, mountains and gardens. At this stage the caterpillar is ravenous and will eat constantly. Most are herbivores and will stick to leaves and other plant matter; however, some will also eat fungi, other parts of the plant, animal matter and even other caterpillars. In fact, the caterpillar can eat up to 27,000 times its own body weight!
The caterpillar is also prey to several species of birds, small rodents, wasps and parasites. It must avoid these and uses camouflage to help remain safe and alive. Some caterpillars have intricate and highly detailed camouflage on their bodies to resemble a plant or twig. When the Hawkmoth caterpillar feels threatened it will pull its legs in and inflate its rear end to resemble a snake. The Swallowtail caterpillar deters its prey by looking like a large blob of bird doodie.
Another way caterpillars defend themselves is by their foul taste. Many of the plants caterpillars eat already produce a toxin that makes them unpleasant. The caterpillar uses these toxins for its own benefit. The Monarch butterfly for example uses the glycosides produced by the milkweed plant in its own body to make it unpalatable to its predators.
As the caterpillar eats, it will grow and can expand its body size up to 1,000 times its original body mass, With all this growing the caterpillar must shed its unpliable skin. Caterpillars can do this several times during their larval stage. After its last shed, the caterpillar will go into the chrysalis stage. Moths will use silk from its body to wrap itself into a cocoon where it will begin its metamorphosis.
The caterpillar may not look muscle-bound, but it has around 4,000 muscles packed into that tiny body – by comparison we only have 629 muscles. The head of caterpillar alone consists of 248 individual muscles and it has 70 muscles to control each body segment. Along with the muscle, the caterpillar has 12 eyes. These eyes or stemmata are arranged in two groups of 6 semicircles on the side of the caterpillar’s head near to its antennae. However, all these eyes does not translate to excellent eyesight, it’s actually quite the opposite. The caterpillar uses its stemmata to tell the difference between light and dark. If you watch a caterpillar you may notice it stands up a bit and moves its head from side-to-side. This is most likely it trying to get some depth perception as to where it is.
This is only the very beginning of all the cool interesting things the caterpillar has to offer. For more information grab a book or check out the internet.
