Direct flight muscles attach to wing bases and move wings directly. This mechanism occurs in some insect groups and allows controlled wing motion.

Cerci are paired appendages at the end of the abdomen in some insects such as cockroaches. They often detect air movements or touch.

The insect thorax is divided into prothorax, mesothorax, and metathorax. Each segment bears a pair of legs, while wings usually attach to the mesothorax and metathorax.

Cursorial legs are adapted for fast running. Their length and shape help insects move quickly across surfaces, useful in predators and escape-oriented species.

Indirect flight muscles do not attach directly to wings. Instead, they change the shape of the thorax, causing the wings to beat rapidly.

The ovipositor is part of the female reproductive system and helps deposit eggs in suitable places. It may be modified for piercing, digging, or stinging in some groups.
