Which insects have a pupa? Types, features of development

Insects are amazing creatures. Some of them amaze with their beauty, others frighten only by sight, others can be useful to a person, and the fourth is a danger to him. It does not matter whether a small creature is harmed or quietly crawls on the ground, without affecting the livelihoods of people: some species of "insects" reproduce in a special way. Which insects have a pupa?

What is a chrysalis?

Pupa is nothing more than the stage of development of a particular individual, characteristic of insects predisposed to complete transformation. While in this state, the insect has a complete change in the organs and tissues belonging to the larva, into the structure of the adult. As a rule, the pupae are immovable, they do not change in size and do not eat.

After completing the growth process, the larva stops eating, goes on to a sedentary lifestyle, the last time it dumps the skin and then turns into a pupa. The appearance of the pupa does not allow us to call it an adult, but it already acquires a list of signs that allow it to be compared to a transformed insect. In most insects, the larva, before becoming a pupa, is wrapped in a cocoon. As a rule, silk is the material for its creation. Cocoons of some species of butterflies are selected for the creation of tissues, such as silk and chchucha. Which insects have a pupa? Their list is quite extensive: the mentioned butterflies, mantises, hornets, wasps, May beetles, house flies, ants and others. We will tell in more detail about some representatives of this group.

Butterfly

Answering a question about what insects have pupae, it is worth paying attention to butterflies. Immediately after the pupa is formed, this insect remains open: its small legs and wings adhere to the body very slightly, they can easily be bent.

However, the soft outer shell quickly hardens, the limbs are firmly adhered to the body with a special liquid. With a superficial examination, the pupa is very similar to the caterpillar, but if you take care, you can see some features of an adult butterfly: the inclinations of the wings, a sketch of the head, abdomen, proboscis and antennae. The durable shell of the pupa, as a rule, is devoid of hair, but some species of butterflies still have individuals decorated with a small amount of them.

Which insects have a pupa, besides a butterfly?

Housefly

The female of this insect at one time is able to put up to 120 eggs, and for the whole life this number increases to two thousand if the environment proves favorable. The egg develops completely within 8-50 hours. The housefly is an insect, predisposed to complete transformation. Its larvae reach a length of thirteen millimeters, do not have legs, the shape of the mouth is pointed, the tip is truncated. They live in feces, as well as in other rotting substances with a semi-liquid structure.

After about two weeks, the larva completes the last molt and crawls into a secluded place, where it turns into a pupa. This phase of life of a housefly lasts about three days. An adult lives up to a month, but under favorable conditions this period can double. At the expiration of one and a half days after the completion of the transformation, the fly is capable of multiplying.

In addition to the fly, which insects have a pupa? There are enough of them.

Ant

In search of information about which insects have a pupa, you can face ants. Their life begins with the appearance of an egg, from which the larvae appear very quickly.

In itself, it practically does not move, it is taken care of by workers: they feed them and transfer them to special "rooms". After passing through all the larval stages, the future ant pupates. The insect is unable to independently get rid of the shell covering the pupa, so adults help it to finally appear.
