LEPIDOPTERA

Lepidoptera is an order of insects which includes the butterflies and moths, and is marked by the following characteristics: - There are four pairs of wings and both they and the body are covered with scales, frequently brightly coloured, which on the body may resemble hairs in appearance. The imago, or perfect insect, is devoid of biting jaws, and usually possesses a long protrusible proboscis. The metamorphosis is well marked, and the larva (caterpillar) has powerful jaws and is almost invariably vegetarian in diet. In the pupa stage the appendages are usually cemented to the body, which is invested by a continuous horny skin, and frequently by a cocoon in addition.
