  2. Metamorphosis - Wikipedia

    en.wikipedia.org/wiki/Metamorphosis

    A dragonfly in its final moult, undergoing metamorphosis, it begins transforming from its nymph form to an adult. Metamorphosis is a biological process by which an animal physically develops including birth transformation or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentiation.

  3. Holometabolism - Wikipedia

    en.wikipedia.org/wiki/Holometabolism

    Holometabolism, also called complete metamorphosis, is a form of insect development which includes four life stages: egg, larva, pupa, and imago (or adult). Holometabolism is a synapomorphic trait of all insects in the superorder Holometabola. Immature stages of holometabolous insects are very different from the mature stage.

  4. Hemimetabolism - Wikipedia

    en.wikipedia.org/wiki/Hemimetabolism

    Hemimetabolism or hemimetaboly, also called partial metamorphosis and paurometabolism, [1] is the mode of development of certain insects that includes three distinct stages: the egg, nymph, and the adult stage, or imago. These groups go through gradual changes; there is no pupal stage.

  5. Insect - Wikipedia

    en.wikipedia.org/wiki/Insect

    Life-cycle of butterfly, undergoing complete metamorphosis from egg through caterpillar larvae to pupa and adult. Holometabolism, or complete metamorphosis, is where the insect changes in four stages, an egg or embryo, a larva, a pupa and the adult or imago. In these species, an egg hatches to produce a larva, which is generally worm-like in form.

  6. Butterfly - Wikipedia

    en.wikipedia.org/wiki/Butterfly

    When metamorphosis is complete, the pupal skin splits, the adult insect climbs out, expands its wings to dry, and flies off. Some butterflies, especially in the tropics, have several generations in a year, while others have a single generation, and a few in cold locations may take several years to pass through their entire life cycle. [3]

  7. Biological life cycle - Wikipedia

    en.wikipedia.org/wiki/Biological_life_cycle

    In biology, a biological life cycle (or just life cycle when the biological context is clear) is a series of stages of the life of an organism, that begins as a zygote, often in an egg, and concludes as an adult that reproduces, producing an offspring in the form of a new zygote which then itself goes through the same series of stages, the ...

  8. External morphology of Lepidoptera - Wikipedia

    en.wikipedia.org/wiki/External_morphology_of...

    Lepidopterans undergo complete metamorphosis, going through a four-stage life cycle: egg, larva or caterpillar, pupa or chrysalis, and imago (plural: imagines) / adult. The larvae – caterpillars – have a toughened ( sclerotised ) head capsule, chewing mouthparts , and a soft body, that may have hair-like or other projections, three pairs of ...

  9. Phasmatodea - Wikipedia

    en.wikipedia.org/wiki/Phasmatodea

    The Phasmatodea life cycle is hemimetabolous, proceeding through a series of several nymphal instars. Once emerged, a nymph will eat its cast skin. Adulthood is reached for most species after several months and many molts. The lifespan of Phasmatodea varies by species, but ranges from a few months to up to three years. [30]
