What is the scarab beetle life cycle?
After a male and female beetle of family Scarabaeidae (scarab beetles, of which there are 30,000 known species) mate, the female lays dozens to hundreds of eggs, which are spherical, ellipsoidal or slightly cylindrical and usually have a diameter of about 1.5 mm. They may be translucent to creamy white with small hexagonal areas on the surface. During embryo development, the egg enlarges to double its initial size and becomes almost spherical. After several days to a month or longer, an egg hatches, and a larva emerges. For the Japanes beetle (Popillia japonica), the larva is translucent and creamy white, the grub is covered with scattered long brown hairs interspersed with short, blunt, spines. The head is yellowish-brown with strong dark-colored mandibles and the body consists of three thoracic and ten abdominal segments. Each thoracic segment bears a pair of segmented legs.
