Now most of the larvæ were turning into Nymphs, which are half-grown Dragon Flies. They had been short and plump, and now they were longer and more slender, and there were little bunches on their shoulders where the wings were growing under their skin. They had outgrown their old skins a great many times, and had to wriggle out of them to be at all comfortable. When a Dragon-Fly child became too big for his skin, he hooked the two sharp claws of each of his six feet firmly into something, unfastened his skin down the back, and wriggled out, leaving it to roll around in the water until it became just part of the mud.
Like most growing children, the Dragon-Fly larvæ and Nymphs had to eat a great deal. Their stomachs were as long as their bodies, and they were never really happy unless their stomachs were full. They always ate plain food and plenty of it, and they never ate between meals. They had breakfast from the time they awakened in the morning until the sun was high in the sky, then they had dinner until the sun was low in the sky, and supper from that time until it grew dark and they went to sleep: but never a mouthful between meals, no matter how hungry they might be. They said this was their only rule about eating, and they would keep it.
They were always slow children. You would think that, with six legs apiece and three joints in each leg, they might walk quite fast, yet they never did. When they had to, they hurried in another way by taking a long leap through the water. Of course they breathed water like their neighbors, the fishes and the Tadpoles. They did not breathe it into their mouths, or through gills, but took it in through some openings in the back part of their bodies. When they wanted to hurry, they breathed this water out so suddenly that it sent them quickly ahead.
The Snapping Turtle had called them "bothering bugs" one day when he was cross (and that was the day after he had been cross, and just before the day when he was going to be cross again), and they didn't like him and wanted to get even. They all put their queer little three-cornered heads together, and there was an ugly look in their great staring eyes.
"Horrid old thing!" said one larva. "I wish I could sting him."
"Well, you can't," said a Nymph, turning towards him so suddenly that he leaped. "You haven't any sting, and you never will have, so you just keep still." It was not at all nice in her to speak that way, but she was not well brought up, you know, and that, perhaps, is a reason why one should excuse her for talking so to her little brother. She was often impatient, and said she could never go anywhere without one of the larvæ tagging along.
"I tell you what let's do," said another Nymph. "Let's all go together to the shallow water where he suns himself, and let's all stand close to each other, and then, when he comes along, let's stick out our lips at him!"
"Both lips?" asked the larvæ.
"Well, our lower lips anyway," answered the Nymph. "Our upper lips are so small they don't matter."
"We'll do it," exclaimed all the Dragon-Fly children, and they started together to walk on the pond-bottom to the shallow water. They thought it would scare the Snapping Turtle dreadfully. They knew that whenever they stuck out their lower lips at the small fishes and bugs, they swam away as fast as they could. The Giant Water-Bug (Belostoma), was the only bug who was not afraid of them when they made faces. Indeed, the lower lip of a Dragon-Fly child might well frighten people, for it is fastened on a long, jointed, arm-like thing, and has pincers on it with which it catches and holds its food. Most of the time, the Dragon-Fly child keeps the joint bent, and so holds his lip up to his face like a mask. But sometimes he straightens the joint and holds his lip out before him, and then its pincers catch hold of things. He does this when he is hungry.
