Lepidoptera The insects included within this order are the moths, the skijipers, and the butterflies. The main characteristic of the order is the fact that the wings and body are (â¢overed with minute scales, which are arranged in definite jiatterns and often give to the wings beautiful and elaborate colors. In all Lepidoptera there is com- plete metamorphosis. The lar\a is conmionly known as a cater- pillar, or simply as a " worm," the latter term more frequently attached to lar\-a"- that are not covered with hairs. Thus, on the one hand, we speak of the cabliage worm and the canker worm, on the other the tent caterpillar and the velLiw-neckcd caterpillar. The larv;v ha^â e three pairs of legs near the front end of the body, a single pair of legs or claspers at the hind end. and usually two to four pau's of fleshy prolegs between. All ailults in the order liave fotir wines, except in cer- tain species where the wings are entirely lacking. The mouth parts. Flu. S-.âScale? from tlio wing of a huttortiy. Enlarged.
