About 200 first- and third-graders at Edna Maguire Elementary School in Mill Valley released some 55,000 ladybugs Thursday into the 1/3-acre Children's Garden to control aphids. Organizer Leslie Myers gave the kids fun facts about the little red- and black-spotted omnivores, which can gobble up to 50 aphids a day, along with mealy bugs and other pests. Ladybugs beat their wings 85 times a second and have a top flying speed of 15 mph. Some live as long as three years. Students come weekly to tend the 25-year-old garden, planted with organic vegetables and fruit trees. All the plants are grown from seeds, and students get to eat the fruits of their labor.
