    • Larva (Zoöl) 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 larvæ 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 larvæ are totally unlike the parents in structure and habits, and are called caterpillars grubs maggots, etc.
    • Larva (Zoöl) The early, immature form of any animal when more or less of a metamorphosis takes place, before the assumption of the mature shape.

    • n larva In zoology:
    • n larva The early form of any animal which during its development is unlike its parent: thus the tadpole, the larva of the frog, is unlike the frog. It is most familiar as the name for an insect in the caterpillar or grub state; the first stage after the egg in the metamorphoses of insects, preceding the pupa or chrysalis; the first condition of an insect at its issuing from the egg, when it is usually in the form of a grub, caterpillar, or maggot. The term was applied by Linnæus in the sense that the larval stage of an insect masks or hides the true character or imago of the species. It was long only or chiefly an entomological term, but is now commonly extended to other animals than insects, and especially other arthropods which undergo transformation. See pupa, imago, and cuts under Asteroidea, Cirripedia, Diptera, glass-crab, hag-moth, Holothuroidea, and house-fly.
    • n larva A genus of mollusks.
    • n larva A genus of birds: same as Alca.
