What are the larval forms of hard-shelled beetles or weevils commonly known as?

The larval forms of hard-shelled beetles or weevils are commonly known as grubs. Grubs typically have a characteristic shape that includes a soft, white body and a curved or C-shape, with a set of legs. This form is adapted for life in the soil or decaying wood, where they consume organic material.

The term "larvae" can refer to the immature forms of many insects, but it does not specifically denote the larval stage of hard-shelled beetles or weevils. Insect larvae can take various forms, depending on the order they belong to, which is why it is less specific for this particular type of insect. Butterflies and caterpillars are also distinctively different, as caterpillars are the larval forms of butterflies and moths, not beetles or weevils. Understanding these classifications is essential in entomology and pest management.
