Each female rice weevil is capable of laying four eggs a day and can produce up to 300 eggs in her lifetime. Females perforate kernels or seeds in order to lay single eggs inside. After doing so, the affected grain is sealed with gelatinous secretions. Larvae consume the kernel from the inside out, leaving behind an emptied husk.
In colder temperatures, the development cycle of the rice weevil may span more than 32 days. However, on average, larvae emerge within three days and develop into pupae within 18. Six days afterwards, adults emerge from the husk. Adults may live as long as six months.
