caterpillar (kăt`əpĭl'ər, kăt`ər–), common name for the larva larva, independent, immature animal that undergoes a profound change, or metamorphosis, to assume the typical adult form. Larvae occur in almost all of the animal phyla; because most are tiny or microscopic, they are rarely seen.

There are about 12 families of butterflies. Most adult moths and butterflies feed on nectar sucked from flowers.

They have three pairs of short, jointed legs (retained in the adult) on the thorax; in addition, they have unjointed, fleshy appendages, called prolegs, on some abdominal segments. The prolegs end in clusters of tiny hooks. There is a row of simple eyes on either side of the body. Sawfly larvae are often mistaken for caterpillars, but their prolegs have no hooks and they have a single simple eye on each side. Almost all caterpillars are vegetarian and have strong jaws for chewing. The chewing mouth parts and the prolegs disappear during the pupa pupa (py

The caterpillar exudes a silk strand continuously as it moves along; small caterpillars swing by the strand when dropping from a height. Many caterpillars use the thread to build a cocoon in which to pupate. Most molt their skin (to accommodate growth) five or six times before pupation. Some caterpillars have smooth skin; others are hairy, such as the woolly bear, or hedgehog, caterpillar of the Isabella tiger moth. The caterpillars of the larger night-flying moths (e.g., the luna moth and polyphemus moth) are smooth and green and may be over 3 in. (7.5 cm) long. Caterpillars are equipped with various protective devices. The io moth caterpillar has sharp spines connected with glands that secrete an irritating substance. Others have irritating bristles, and the swallowtail butterfly larva emits a repellent odor when disturbed. Nevertheless, caterpillars form the major part of the diet of many birds and other animals. Caterpillars are voracious eaters and some cause considerable economic damage. Among these are the appleworm, the cutworm cutworm, name for the larvae of many moths of the family Noctuidae (owlet moths). These larvae, or caterpillars, feed at night on the stems and roots of young plants, often cutting them off near the surface of the ground. They hide in soil by day.

caterpillar

Larva of a butterfly or moth. Caterpillars have a cylindrical body consisting of 13 segments, with three pairs of legs on the thorax and “prolegs” on the abdomen. The head has six eyes on each side, short antennae, and strong jaws. Though not true worms, many caterpillars are called worms (e.g., the inchworm, or looper, and the cutworm). Caterpillar-like larvae are also found in other insect groups (e.g., sawflies and scorpionflies).
