A change in insect ages with an incomplete stage of transformation is associated with a large number of lines, when insects get rid of the old cuticle, which is then replaced by a new. This process helps them to gradually increase their size. In case of incomplete transformation of the difference between representatives of various stages, they are not so pronounced. For example, the larvae of most insects resemble the same adults, but in a reduced version. However, the features of metamorphosis vary depending on the type of view under consideration. For example, a larva and an imago dragonfly look completely different. The similarity of the stages is inherent in primitive flawless representatives of insects, the changes of which are associated only with an increase in growth. Incomplete transformation is characteristic of insects such as bugs, straightwinged, equivalents, dragonflies, praying mantis, cockroaches, spring, earwovers, subscriptions and lice.
We offer to familiarize yourself with all representatives of insects with incomplete transformation.

Differences from complete transformation
Despite the lack of an intermediate stage characteristic of complete transformation, insects with incomplete transformation are absolutely the same insects. The number of stages, the speed of transition and other features are associated only with the habitat of insects. For example, stages of aphid development are determined by the number of available food supplies throughout the development.
With complete transformation, insects have cardinal external differences at all stages of development, while insects with incomplete metamorphosis have a slightly less significant difference in appearance.
In larvae with incomplete transformation, a pair of complex eyes is located and the structure of the device of the rotary apparatus is the same as that of the imago. The larva in front of the Imago stage passes through 4 or 5 Linek, and some species reach this stage after 20 lines. Because of this, various types of insects vary in the number of phases of development of the larvae.
Some insects have a complicated incomplete transformation, namely hypermorphosis. This phenomenon is characterized by the fact that nymphs appear at the stage of larvae.
