Ladybugs are beetles. They are small oval-shaped insects with wings. Sometimes they are called ladybirds or lady beetles. What is a ladybug?
Have you ever wondered how the ladybug got its name? There is a legend that during the Middle Ages, swarms of pests were destroying crops, so farmers prayed to the Virgin Mary, the mother of Jesus, for help. Soon after, ladybugs came and ate the bad pests and saved the crops. The farmers called these bugs, "Beetles of Our Lady" and they eventually became known as "ladybugs”. In many countries, ladybugs are considered to be good luck. Legend of the Ladybug’s Name Say it in Spanish - Mariquita
