Stages of complete conversion of insects

Various metamorphoses are characteristic of all types of insects. Complete transformation involves an absolute change in the appearance of an insect. During the period of change of phases of complete transformation, all insects are experiencing several stages of molting. Such shifts are inherent in beetles, scales, flies. The usual complete transformation looks as follows: bursting, insects drop the old cuticle and begin to increase in size. Such periods have different time intervals. For example, butterfly larvae pass 5-6 lines that indicate their age.

The main stages of the transformation:

Egg. This phase is characterized by the stay of the embryo inside the hard shell of the egg. At this stage, it replenishes the reserves of nutrients and is preparing to go to the next stage. The completion of this period is the exit of the larva from your egg.

Larva. Unlike the embryo, the larva begins to move and acquires the opportunity to eat on its own. As a rule, the appearance of the larva is very different from other stages. This is due to the underdevelopment of many organs. The main task of this stage is to nutrition in order to increase its size. Some insects have cannibalism among young individuals. After the stage of the egg, larvae can eat each other in the absence of other organisms;

Puppet. In this stage, insects do not move and are in the shell of the doll. The body of insects is experiencing serious changes in the anatomy of the structure of the body, and upon completion, insects become adults. If you try to open the larva at the first stage of the doll, then it will be difficult to notice some development in it. The doll will consist of thick white liquid, and from organs it will be possible to see only the vascular and nervous systems. This fluid serves to build a fullfledged organism.

Imago. Fully formed body of an insect. Has all the necessary organs inherent in the specific type.

The difference in complete and incomplete transformation

During the period of incomplete transformation, insects pass three stages that are similar to metamorphoses of complete transformation, with the exception of the stage of the “doll”. With incomplete transformation, the differences between the stages are not so pronounced. The larva looks like a small adult individual. However, despite a small number of stages of transformation, insects with incomplete metamorphoses are as fullfledged as insects with complete transformation. The presence of certain phases is explained by the conditions of the existence of insects. The detachments of insects with incomplete transformation include: equivalents, bugs, dragonflies, lice, straightwinged, cockroaches.

Features of the development of insects with complete transformation

The cardinal difference of larvae from the last stage is noteworthy. Larvae are completely characterized by the territory and food from the imago. For example, larvae of flies and beetles live in the soil. In addition, the larvae of complete transformation of the gnawing oral apparatus, there are no eyes and rudiments of the wings, and the antennae and legs are very short. The degree of development of the limbs depends on the type of insects and divided into 4 groups:

Fengory larvae. Characteristic of doublewinged and beetles;

Larvae with small rudiments of the limbs. These include bees and wasps;

Larvae with welldeveloped limbs. This type is demonstrated by the individuals of winged insects, for example, beetles and meshwinged;

Caterpillar. This stage has excellently developed three pairs of walking legs and several pairs of false knives. These include representatives of butterflies and sawmills.

The characteristics of the development stages of a particular phase may differ depending on the type of view under consideration.
