Based on your answers to the questions, you have identified your insect as being in the family Tetrigidae of the order Orthoptera!

General characteristics:
A large pronotum is a characteristic of this family. The pronotum typically extends far back over the abdomen.

Many members of the family Tetrigidae have very small forewings that may or may not be easily visible. Therefore, the pygmy grasshoppers often appear to have only two wings. Other than the very reduced (or missing) forewings, the pygmy grasshoppers share all of the other characteristics of their order, which is Orthoptera.
