The larvae of which beetles are commonly referred to as grubs?

The larvae referred to as grubs primarily belong to Japanese beetles. These grubs are the immature stages of the beetles and have a characteristic C-shaped appearance. They typically live in the soil and feed on the roots of various plants, which can cause significant damage to lawns and gardens.

In contrast, ladybugs, ants, and wasps do not have life stages that are commonly termed as grubs. Ladybugs are known for their larvae resembling tiny alligators, which prey on pests like aphids. Ants have a larval stage but are generally described as larvae rather than grubs. Wasps, while they do have larvae, also do not use the term grubs to describe them. Understanding these distinctions is important for effective pest management and identification in the context of pesticide application and control.
