THE NIGHT MOTH'S PARTY

From the time when she was a tiny golden-green Caterpillar, Miss Polyphemus had wanted to go into society. She began life on a maple leaf with a few brothers and sisters, who hatched at the same time from a cluster of flattened eggs which their mother had laid there ten days before. The first thing she remembered was the light and color and sound when she broke the shell open that May morning. The first thing she did was to eat the shell out of which she had just crawled. Then she got acquainted with her brothers and sisters, many of whom had also eaten their egg-shells, although two had begun at once on maple leaves. It was well that she took time for this now, for the family were soon scattered and several of her sisters she never saw again.

She found it a very lovely world to live in. There was so much to eat. Yes, and there were so many kinds of leaves that she liked,—oak, hickory, apple, maple, elm, and several others. Sometimes she wished that she had three mouths instead of one. In those days she had few visitors. It is true that other Caterpillars happened along once in a while, but they were almost as hungry as she, and they couldn't speak without stopping eating. They could, of course, if they talked with their mouths full, but she had too good manners for that, and, besides, she said that if she did, she couldn't enjoy her food so much.

You must not think that it was wrong in her to care so much about eating. She was only doing what is expected of a Polyphemus Caterpillar, and you would have to do the same if you were a Polyphemus Caterpillar. When she was ten days old she had to weigh ten times as much as she did the morning that she was hatched. When she was twenty days old she had to weigh sixty times as much; when she was a month old she had to weigh six hundred and twenty times as much; and when she was fifty days old she had to weigh four thousand times as much as she did at hatching. Every bit of this flesh was made of the food she ate. That is why eating was so important, you know, and if she had chosen to eat the wrong kind of leaves just because they tasted good, she would never have become such a fine great Caterpillar as she did. She might better not eat anything than to eat the wrong sort, and she knew it.

Still, she often wished that she had more time for visiting, and thought that she would be very gay next year, when she got her wings. "I'll make up for it then," she said to herself, "when my growing is done and I have time for play." Then she ate some more good, plain food, for she knew that there would be no happy Moth-times for Caterpillars who did not eat as they should.

She had five vacations of about a day each when she ate nothing at all. These were the times when she changed her skin, crawling out of the tight old one and appearing as fresh and clean as possible in the new one which was ready underneath. After her last change she was ready to plan her cocoon, and she was a most beautiful Caterpillar. She was about as long as a small cherry leaf, and as plump as a Caterpillar can be. She was light green, with seven slanting yellow lines on each side of her body, and a purplish-brown V-shaped mark on the back part of each side. There were many little orange-colored bunches on her body, which showed beautiful gleaming lights when she moved. Growing out of these bunches were tiny tufts of bristles.

She had three pairs of real legs and several pairs of make-believe ones. Her real legs were on the front part of her body and were slender. These she expected to keep always. The make-believe ones were called pro-legs. They grew farther back and were fat, awkward, jointless things which she would not need after her cocoon was spun. But for them, she would have had to drag the back part of her body around like a Snake. With them, the back part of her body could walk as well as the front, although not quite so fast. She always took a few steps with her real legs and then waited for her pro-legs to catch up.

As the weather grew colder the Polyphemus Caterpillar hunted around on the ground for a good place for her cocoon. She found an excellent twig lying among the dead leaves, and decided to fasten to that. Then began her hardest work, spinning a fluffy mass of gray-white silk which clung to the twig and to one of the dry leaves and was almost exactly the color of the leaf. Other Caterpillars came along and stopped to visit, for they did not have to eat at cocoon-spinning time.
