Larva
['lɑːvə] or ['lɑrvə]
解释:
(noun.) the immature free-living form of most invertebrates and amphibians and fish which at hatching from the egg is fundamentally unlike its parent and must metamorphose.
黛安娜校对--From WordNet
解释:
(n.) Any young insect from the time that it hatches from the egg until it becomes a pupa, or chrysalis. During this time it usually molts several times, and may change its form or color each time. The larvae of many insects are much like the adults in form and habits, but have no trace of wings, the rudimentary wings appearing only in the pupa stage. In other groups of insects the larvae are totally unlike the parents in structure and habits, and are called caterpillars, grubs, maggots, etc.
(n.) The early, immature form of any animal when more or less of a metamorphosis takes place, before the assumption of the mature shape.
