The nymph is one of the stages of insect
metamorphosis
The nymph is one of the physiological states of an
insect that follows the larval stage, by which it then becomes an adult that
can fly and reproduce. It is one of the stages of complete metamorphosis
insects during which it changes a lot of appearance to take its final adult
form.
The various metamorphoses of organisms of the
insect class are necessary for their evolution. The egg that is laid according
to the ritual of the species becomes a larva, which will eat continuously to
grow and moult. The caterpillar is one of the forms that a larva takes, but it
does not necessarily always have this form for all orders of insects.
The nymph state follows the larval state, and
according to the species, it will have an appearance of its own. For some, it
takes this form for a while, relatively short or long. It is during this phase
that the wings and other parts of the adult's body appear. In Ephemeroptera, we
speak of subimago, which is the stage that precedes their adult form. In the
Hymenoptera, the Coleoptera, we speak of a free nymph who is white and
motionless until it develops into an adult.
Cocoons of butterflies
Cocoons of butterflies
In Lepidoptera, it uses silk threads to secrete and
weave a cocoon around her to protect herself during her passage as a nymph
mummy, which is actually called a chrysalis. Enveloped in its cocoon, the
chrysalis will then turn into the adult insect, the imago, and we do not see
them during this state of transformation. Depending on the species of insect,
the development of this metamorphosis can last a few days, or weeks.

During this period of growth, the nymph usually
does not eat because its entire system is changing, and even the digestive
system and its mouthparts can be affected. That's why the larvae eat
continuously to provide their body with all the nutrients and energy needed for
this step. In flies, the nymph is called a pupa, which is the equivalent of the
chrysalis for butterflies, where it is transformed into an envelope that
protects it.

The appearance and size of the nymphs vary
according to the family, and even the species of insect that is in
metamorphosis. Nymphs are also used for incompletely metamorphosing insects
that resemble their adult form, but whose tiny wings are not usable until they
have developed, as is the case with many Hemiptera. Others are really different
from their adult form and it is only through experience that we can identify
them. The size, color, patterns, shape, season ... are clues used to identify
the species to which a nymph belongs.
Cicada nymph
Cicada nymph
Some insects, such as dragonflies, have aquatic
nymphs and live in water until they reach adulthood. The ladybug larvae look
like little caterpillars, then settle on a leaf where it stays stuck for a while
to moult, then comes out of her nymph skin once her adult makeover is over.
Nymphs are a great source of food for all orders
and families of animals. Their more limited means often make them easy prey,
and they are important for many species in the food chain.
