It is known as metamorphosis to the change that occurs in the structure of an individual belonging to a species, the etymological origin of this term comes from the Greek "metamorphosis" which means "after the form"; This terminology has its leading role in the area of biology and is applied to refer to the transformation that animal species make until they reach an adult stage, the insect species being the one that undergoes the greatest metamorphosis with respect to the others that make up the kingdom animal.
According to the severity of the changes, metamorphosis can be classified into two types: holometabola and hemimetabola; When we refer to a holometabolic metamorphosis, it is to mention a total transformation where the egg or initial form of that living being is totally different from the adult stage, for example: mosquitoes, they go from eggs to pupae later they acquire the form of larvae and finally to adult mosquito. Another insect that performs a holometaball transformation is the butterfly: it has an egg stage, which can be seen perched near a plant, this stage is where it needs more nutrients, therefore it stays there to receive food; larval stage (caterpillar) the insect has already developed a mouthpart that allows it to consume its nutrients, this being the stage of greatest growth, pupal stage where it acquires the shape of a cocoon where it remains closed for 5 days until its adult stage where it already has wings and takes on the traditional butterfly shape.
On the other hand, hemimetabola metamorphosis refers to a more radical transformation where the initial form of the species is similar to the adult stage, however the only difference is the size of both, for example: lice, they pass from eggs to nymphs (nits) and subsequent to an adult louse; species of class insecta order Diptera (winged) when in nymph form do not yet have their wings. Another example of a hemimetabolic metamorphosis is the frog: it initially acquires the form of a nymph (tadpole) where it remains in the water until it reaches its ideal size, this being its crucial growth stage until its adult stage as a frog where its legs and legs develop. their lungs, allowing them to live outside the water.
