What is a grub?

A grub is the larval stage of an insect, typically a beetle or moth. Grubs are cream-colored, C-shaped creatures with six legs and a head that is well-defined from the rest of its body. They feed on plant roots, decaying organic matter, and other organic material found in soil. Grubs are considered pests in agriculture and gardening, as they can cause damage to crops and lawns by feeding on roots. They are also a common food source for many animals, such as birds, frogs, and other insects. In some cultures, grubs are also eaten by humans as a source of protein.
