The immature or worm stage of an insect that passes through four stages (egg, larva, pupa, adult) is referred to as what?

• A. Larva
• B. Insect
• C. Lesions
• D. Inversion

Answer: (A)

Insects that undergo complete metamorphosis go through four life stages: egg, larva, pupa, and adult. The immature, worm-like stage is called a larva. This is the feeding and growth phase that looks very different from the adult and will later become a pupa before turning into an adult. The other terms don’t fit: a general insect is the whole organism, not a developmental stage; lesions are skin or tissue abnormalities; inversion refers to turning something inside out, not a developmental stage.
