The orthoptères (of the Greek ortho , right, and ptéron , wing) are animal Arthropode S of the class of the Insecte S, characterized by right wings. The order includes the Sauterelle S, Courtilière S, cricket S and the Criquet S among which one distinguishes the Locuste S and the Sauteriau X. Many insects of this kind produce a sound (process of Stridulation), some have developed legs posterior which their make it possible to carry out great jumps.

Biological features common to the order of the orthoptères

99% of the known species are Phytophage S.

Systematic

Old classification

In old classifications, the Orthoptères (insects with the right wings) are an order of Insecte S, subclass of the Ptérygote S, section of the Néoptère S, superorder of the Orthoptéroidé S.

Orthoptères are characterized by:

• a incomplete metamorphosis, (Paurométabolisme), namely, that the larvae and the adults resemble each other, the difference being done on the level of the color and the appearance of wings at the adulthood. In the same way they carry out both the same way of life, (even medium) by Hemimétabolisme opposition where adult and larva carry out a different lifestyle. Such as for example here the butterflies (Lepidoptera) and the dragonflies (Odonates).
• of the posterior wings, with symmetrical folds, which are folded up like a range under the tegmina (corresponding to the élytres ches the Coléoptère S).
• of the posterior legs very developed and equipped with a powerful musculature which their make it possible to jump.
• a stridulation obtained by the friction of the posterior legs against the élytres (locusts, grasshoppers) or use of a stridulant apparatus differentiated on the élytres (crickets).
