Nobody knows why they should have been called Frog-Hoppers, unless it was because when you look them in the face they seem a very little like tiny Frogs. To be sure, they have six legs, and teeth on the front pair, as no real Frog ever thought of having. Perhaps it was only a nickname because their own name was so long and hard to speak.
The golden-rod was beginning to show small yellow-green buds on the tips of its stalks, and the little Frog-Hoppers were now old enough to talk and wonder about the great world. On one stalk four Frog-Hopper brothers and sisters lived close together. That was much pleasanter than having to grow up all alone, as most young Frog-Hoppers do, never seeing their fathers and mothers or knowing whether they ever would.
These four little Frog-Hoppers did not know how lucky they were, and that, you know, happens very often when people have not seen others lonely or unhappy. They supposed that every Frog-Hopper family had two brothers and two sisters living together on a golden-rod stalk. They fed on the juice or sap of the golden-rod, pumping it out of the stalk with their stout little beaks and eating or drinking it. After they had eaten it, they made white foam out of it, and this foam was all around them on the stalk. Any one passing by could tell at once by the foam just where the Frog-Hoppers lived.
One morning the oldest Frog-Hopper brother thought that the sap pumped very hard. It may be that it did pump hard, and it may be that he was tired or lazy. Anyway, he began to grumble and find fault. "This is the worst stalk of golden-rod I ever saw in my life," he said. "It doesn't pay to try to pump any more sap, and I just won't try, so there!"
He was quite right in saying that it was the worst stalk he had ever seen, because he had never seen any other, but he was much mistaken in saying that it didn't pay to pump sap, and as for saying that "it didn't pay, so there!" we all know that when insects begin to talk in that way the best thing to do is to leave them quite alone until they are better-natured.
The other Frog-Hopper children couldn't leave him alone, because they hadn't changed their skins for the last time. They had to stay in their foam until that was done. After the big brother spoke in this way, they all began to wonder if the sap didn't pump hard. Before long the big sister wiggled impatiently and said, "My beak is dreadfully tired."
