Phyllophaga spp., commonly known as "blind hen," are beetles whose larvae cause significant damage to various crops. These insects go through a complete metamorphosis that includes the egg, larva, pupa and adult stages. Adults emerge from the ground in the spring and summer, feed on the leaves of trees and shrubs, and mate. Females lay eggs in the soil, from which larvae emerge that feed on plant roots for one to three years, depending on the species and environmental conditions. The larvae, which are large, white and C-shaped, are mainly responsible for the damage, as they feed intensively on the roots, weakening the plants and making them more susceptible to diseases and environmental stress. After completing larval development, they pupate in the soil and eventually emerge as adults, completing the cycle.
