Lisa Cusick, age 12, of St. Paul, Minn., for her question:

ARE THERE MALE LADYBUGS?

More than 250,000 kinds of beetles have been discovered  it's the largest order of insects in the world. And the one who doesn't have a human enemy in the world is the ladybug, who is also called a ladybird.

There are indeed male ladybugs, but you don't hear them demanding a name change to " personbug. " They are happy to be male ladybugs, thank you.

Farmers and gardeners especially love ladybugs because the colorful little creatures eat aphids, scale, insects, mites and similar destructive forms of pests. They live and do good work in almost all countries of the world.
