Insects are amazing creatures. Some of them are striking in their beauty, others scare with just one look, others can be useful to a person, and others are dangerous for him. It doesn’t matter if a small creature harms or crawls peacefully on the ground without affecting people's livelihoods: some types of “insects” reproduce in a special way. Which insects have a pupa?
What is a chrysalis?
Pupa is nothing but the stage of development of a particular individual, characteristic of insects predisposed to complete transformation. While in this state, the insect undergoes a complete change in the organs and tissues belonging to the larva into the structure of an adult. As a rule, pupae are motionless, they do not change in size and do not eat food.
Having completed the growth process, the larva ceases to feed, goes on to a sedentary lifestyle, for the last time sheds its skin, and only then turns into a chrysalis. The appearance of the pupa does not allow calling it an adult, but it already has a list of signs that make it possible to compare it with a transformed insect. In most insects, the larva is wrapped in a cocoon before turning into a chrysalis. The material for its creation is, as a rule, silk. Cocoons of some butterfly species are selected to create fabrics such as silk and scabbard. Which insects have a pupa? Their list is quite extensive: the mentioned butterflies, praying mantises, hornets, wasps, May bugs, house flies, ants and others. We will tell you more about some representatives of this group.
Butterfly
Answering the question about which insects have pupae, it is worth paying attention to butterflies. Immediately after the formation of the pupa of this insect, it remains open: its small legs and wings adhere very weakly to the body, they can be easily bent.
However, the soft outer shell hardens quickly enough, the limbs are firmly glued to the body with a special fluid. On superficial examination, the pupa is very similar to a caterpillar, but if you pay attention, you can notice some features of an adult butterfly: the makings of wings, a sketch of the head, abdomen, proboscis and antennae. The robust shell of the pupa is usually 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 is capable of laying up to 120 eggs at a time, and in all its life this number increases to two thousand if the environment is favorable. The egg develops completely within 8-50 hours. Indoor fly - an insect predisposed to complete transformation. Its larvae reach a length of thirteen millimeters, have no 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 its last molt and crawls into a secluded place, where it turns into a chrysalis. This phase of the life of a housefly lasts about three days. An adult lives up to a month, but under favorable conditions, this period can be doubled. After a day and a half after the conversion is completed, the fly is able to multiply.
Besides the fly, which insects have a pupa? There are enough of them.
