The Orthoptera are an order of insects with incomplete metamorphosis, including the grasshoppers, cricketss, locusts, and katydids. Many insects in this order produce sound by rubbing their wings against each other or their legs, the wings or legs containing rows of corrugated bumps. Their ears, located in the front legs, are interconnected in such a way that they are able to locate each other by sound.

The Orthoptera are the only insects considered kosher in Judaism. Although the Bible may be read as stating that all Orthoptera are kosher except those, such as the mole cricket, that do not jump, halakhic authorities state that only four species known in Yemen are kosher.
