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