Ladybug - Aphids beware! One ladybug can devour several thousand aphids in one summer. Adults overwinter under boards or stones. In spring, they lay small orange eggs that hatch into black-&-red larvae that resemble tiny alligators. Larvae & adults are carnivorous, & will also eat scale insects, mealybugs, & mites. When alarmed, ladybugs secrete a foul-tasting fluid from their legs that discourages predators from eating them.
