What is true about immature insects?

The assertion that immature insects can be referred to as larvae in complete metamorphosis is accurate because, in this type of life cycle, immature insects develop through distinct stages: the egg, larva, pupa, and adult. Insects that undergo complete metamorphosis, such as butterflies or beetles, have a larval stage that is markedly different from the adult form. During this larval stage, the insect is primarily focused on growth and feeding, preparing for the next stage of development, which will occur after the pupal stage. This transformation from larva to pupa and finally to adult is pivotal in their life cycle.

The other options present misconceptions about immature insects. Some immature insects do undergo transformations, contrary to the first statement. Wings are typically not present in the larval stages of insects, which makes the statement regarding wings inaccurate. Additionally, immature insects are usually smaller than their adult counterparts; they grow in size as they progress through their life stages.
