Grubs are the larval stage of various insects, particularly beetles. They are typically soft-bodied, white or cream-colored, and have a C-shaped appearance. Grubs live in soil or decaying organic matter, where they feed on roots, leaves, and other plant material. This feeding can sometimes cause damage to gardens and lawns. Grubs undergo a transformation process called metamorphosis, eventually turning into adult insects. Common types of grubs include those from the Japanese beetle and June beetle. While they can be pests, grubs also play a role in the ecosystem by breaking down organic matter and enriching the soil.
