A caterpillar is the larval form of a member of the order Lepidoptera, the insect order comprising butterflies and moths. Like other insects, the caterpillar consists of three body parts, the head thorax and abdomen. The thorax and abdoment are segmented. They have three pairs of true legs on the three thoracic segments, up to four pairs of prolegs on the middle segments of the abdomen, and often a single pair of prolegs on the last abdominal segment. There are ten abdominal segments. Caterpillars breathe through slits in their thorax and abodmen which are called spirales, and move along by flexing a series of approximately 4000 muscles. They also have remarkably good eyesight, since they have six small eyes on each side of their head. Of course, they are voracious plant eaters and are viewed as a pest to crop growers. Caterpillars have developed all kinds of defense mechanisms against predators. Some have spiny, stinging hair, others put off a noxious odor. In any case, caterpillars are amazing creatures, especially in the way they transform into butterflies or moths.
