larva
含义: The immature, wingless, and often worm-like form of an insect or other organism that undergoes metamorphosis before reaching its adult stage.
In biology, a larva is a distinct juvenile stage that differs markedly in form and ecology from the adult. The plural is 'larvae' (Latin) or less commonly 'larvas.' The term applies broadly across zoology, from insect caterpillars and grubs to the tadpoles of amphibians and the planktonic stages of marine invertebrates.
