Millions of kinds of insects live in the rainforest. It never gets cold enough to kill them. There are bees, butterflies, termites, beetles, and many kinds of flies. There are ants everywhere. One kind of ant is the army ant. Army ants do not have nests. They march out in a line every day to hunt for other insects, which they eat. At night they hook themselves together to form a living nest around their queen and larvae, or baby ants.
