Heather Freeman, age 10, of Jackson, Miss., for her question:

WHAT DOES A TREE FROG EAT?

Tree frogs spend much of their lives in trees. There are several hundred kinds of tree frogs. They range in size from less than one inch in length to about five inches long. All of the tree frogs eat insects.

You'll find lots of tree frogs in North and South America and Australia. They have sticky pads on their feet and can climb trees and even leap through the treetops.

Tiny sticky disks on the tree frog's feet are called adhesive disks. Like the chameleons, tree frogs protect themselves by changing color to blend in with their surroundings.

Tree frogs can be heard through much of the summer. When the male calls, his throat swells until it looks as though it were a bubble about to burst. Then the frog makes the call that is characteristic of its species. This sound is hard to locate, even though it may be nearby. Male tree frogs do all the calling.

Tree frogs may be kept in aquariums or terrariums, and fed chopped earthworms or hamburger. In this way, they will be active through the winter and will not hibernate, as do the frogs that live outdoors.
