[R] Order of medium-sized to large insects with relatively primitive chewing mouthparts provided with conspicuous palps; prothorax large; hind legs usually modified for jumping. Almost all Orthoptera are phytophagous. The majority of males possess stridulating organs.
With some exceptions, the Ensifera (grasshoppers, crickets, mole crickets) have long antennae and a well-developed oviscapt. The Caelifera (locusts) are provided with short antennae and a short ovipositor. The Orthoptera are very polyphagous pests.
In addition to migratory locusts, which sometimes occur in the south of France, Gryllotalpa gryllotalpa is the only important pest of this order.
