With Examples, Explain The Difference Between Complete Metamorphosis and Incomplete Metamorphosis.
In their growth and development, some animals undergo metamorphosis. Complete and incomplete metamorphosis are two different types. Does anyone know the difference between complete and imperfect metamorphosis?
Metamorphosis is a gradual change in physical structure from larva to adult. According to the book Natural Sciences by Wasis and Sugeng Yuli Irianto, metamorphosis occurs in insects and amphibians.

Frogs are an example of an amphibian that undergoes metamorphosis. The zygote is the starting point for the growth and development of frogs. After that, the zygote grows into an embryo.
After a week, larvae develop, which are commonly called tadpoles. At first tadpoles or tadpoles breathe using three external gills. The tadpole will then use its deep gills to replace breathing. The gill covers and hind legs develop later.
Tadpoles undergo metamorphosis after three months. Tadpole metamorphosis is characterized by the development of lungs and four legs, loss of gills and tail, until transformation into a frog.
Tadpoles have different personalities from frogs. Tadpoles are herbivores in water, but frogs are carnivores on land.
Insects undergo metamorphosis.
Larvae are newly hatched insects. Butterflies and dragonflies, for example, have a larval phase that is very different from the adult form.
Butterfly larvae called caterpillars, which have chewing-type mouths, represent a contrast between the larvae and the adult form. Butterflies, on the other hand, have sucker-like mouths. Dragonfly larvae live in water, but adults can fly and live on land.
Although different, some insects have almost the same shape when they hatch as adults. Grasshoppers, cockroaches, and crickets are examples.
Insect metamorphosis can be categorized into two types based on the process: complete metamorphosis and incomplete metamorphosis.
What is the difference between complete metamorphosis and incomplete metamorphosis?
The first difference is that complete transformations are distinguished by the pupa or chrysalis phase. Egg -> larva -> pupa (cocoon) -> adult is a complete transformation stage (imago).
Incomplete metamorphosis, on the other hand, is distinguished by the absence of a pupal phase. Egg -> nymph (newly hatched insect) -> adult is a stage of partial metamorphosis (imago)
The second difference is that the adult insect larvae form very differently during complete metamorphosis. Caterpillars and butterflies are two examples. Caterpillars are larvae that hatch from butterfly eggs. Caterpillars are not the same as butterflies.
Definition of Metamorphosis–
Meanwhile, in incomplete metamorphosis, the newly hatched nymphs or insects have a morphology similar to that of adult insects or imago.
The main difference between nymphs and adults is that nymphs do not have wings. The wings will gradually grow larger until they resemble their adult form. In general, nymphs and adults have the same characteristics.
Caterpillar larvae are wingless at this stage of metamorphosis, and there is no evidence of wing formation. Insect larvae are very busy eaters when they are in larval form.
After that, the larva turns into a cocoon. There are larvae that immediately produce pupae, there are also those who seek protection from leaf folds, fine soil or sand, fine wood incisions, and others before making pupae. A cocoon or cocoon is a protective cocoon that surrounds the cocoon.
Insects do not consume actively while in the pupa stage, but the metabolic process continues. The lice will become adults after passing through the pupa stage (imago).
Examples of complete and imperfect metamorphosis
Butterflies, flies, mosquitoes, bees, and beetles are examples of complete transformations. Crickets, cockroaches, and grasshoppers are examples of incomplete metamorphosis.
Do you know what the difference between complete and imperfect metamorphosis is? What creatures did you observe going through the transformation process?
