Stingby

Stingbies are small bee-like enemies with large eyes, having their stinger located on their face.

Super Mario 3D Land
Stingbies make their debut in Super Mario 3D Land. They are common in levels taking place in the sky or over large pits. Stingbies fly at a certain height and cannot move up or down; rather, they patrol the area to find Mario or Luigi. When a Stingby spots Mario or Luigi, they chase after them slowly. These enemies can be easily defeated by any form of attack. They slightly resemble Diggas from Super Mario Galaxy 2.

Mario Kart 7
Stingbies make another appearance in Mario Kart 7. They serve as enemies in the battle course, Honeybee Hive. They have a darker color than those in Super Mario 3D Land. They travel in lines through the stage and spin out any fast-moving karts they touch.

Super Mario 3D World
Stingbies are set to appear in the upcoming Wii U game, Super Mario 3D World.
