The scarab beetle is one of the smallest and most fascinating transparent creatures in the world. It is only 5 to 8 mm long and is similar in shape to a ladybug. Petunias can be seen everywhere in the garden in the morning. Petunia is their favorite food. They can change the color of their bodies and look like miniature jewels or golden ladybugs. By changing the reflective layer of their bodies, their outer wings become transparent. This miniature beetle is quite similar to the golden probe in the Quidditch competition in Harry Potter. It is often seen in southern China, for example, in Yangjiang City, Guangdong Province, when rice is ripe. It is almost as big as a ladybug and can fly. At first glance, it looks like a little turtle, so it is called "Scarab" locally.
