Patricia Greenweli, age 11, of Annapolis, Md., for her question:

HOW DID THE KATYDID GET ITS NAME?

The katydid is one of several species of long horned grasshoppers found in the Western Hemisphere. The name is meant to represent the characteristic sound made by the male when it rubs its wings together to attract females.

Katydids are tree living insects most commonly heard at night during the summer. They are generally about two inches long and green in color, with long antennas. The antennae are called "horns."
