  1. Butterflies, flies, bees and beetles have a 4 stage life cycle that includes egg, larva, pupa and imago. There are three kinds of metamorphosis: ametabolism, hemimetabolism and holometabolism. All the three kinds can be seen in insects. Read this article to get an insight on types of metamorphosis.

  2. Metamorphosis: When the young one does not resemble the adult, such a young one is known as a larva or nymph, it is known as indirect development. The change from nymph or larva to adult is called metamorphosis. The transformation of a larva into an adult is characterized by a series of sudden morphological, physiological, and behavioral changes.

  3. Complete metamorphosis comprised of a very active, ferociously eating larva and an inert pupa. Three phases comprise incomplete metamorphosis: egg, nymph, and adult. The four phases of complete metamorphosis are egg, larva, pupa, and adult. Incomplete metamorphosis permits some of the insect’s exoskeleton to persist throughout its life cycle.

  4. Metamorphism in Frogs. Metamorphism is a hormonal effect. Metamorphism in frogs is controlled by the hormones called thyroxine, and it is produced by the gland called the thyroid. For the production of thyroxine, the thyroid gland needs iodine. Frogs need to live in water bodies where sufficient iodine is present for thyroxine production.

  5. Complete Metamorphosis. As stated before, fleas go through complete metamorphism, which means it has four stages in its life cycle, namely: Egg stage. Larvae stage. Pupa stage. Adult stage. Typically, fleas go through these stages in 14 to 140 days depending on the weather conditions and other environmental factors.

  6. Since complete metamorphism includes four stages of development – egg, larva, pupa and adult, the dragonfly falls under the incomplete metamorphism with three stages – egg, the nymph and the adult. The Egg: A dragonfly begins their life in or near water in the form of eggs. After mating between the male and female dragonfly, the female ...

  7. Hemimetabolous. It refers to insects that show incomplete metamorphosis or hemimetabolism. Their life cycle includes egg, nymph, imago or adult. The pupal stage is absent. The nymphs or naiads undergo gradual metamorphism and turn into adults. There are many hemimetabolous insects like grasshoppers, praying mantises, mayflies, damselflies, etc.

  8. Life Cycle of a Butterfly. 1) The Egg – Stage 1: The female butterfly lays the egg on the surface of a leaf or a stem. The egg is tiny, oval or cylindrical and varies in colour. The popular larvae form of a butterfly known as the caterpillar gradually grows inside the egg. These eggs hatch according to the favourable conditions outside, if it ...

  9. Grasshoppers are hemimetabolous insects. Hence, their life cycle consists of three stages – the egg, the nymph, and the adult. This type of life cycle, where there are three stages is called incomplete metamorphosis; on the other hand, a complete metamorphosis has four distinct stages. Related link: Dragonfly Life Cycle .

  10. Metamorphosis: Metamorphosis in insects can be defined as the change in physical and structural form from the larval stage to the adult stage. The hormone ecdysone is responsible for metamorphosis in insects such as butterflies. This hormone helps in the molting or shedding of old body parts for the formation of new physical forms.
