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.

Super Mario 3D World
Stingbies reappear in Super Mario 3D World in several levels. They behave the same as they do in Super Mario 3D Land. They first appear in World 1 in the level Switch Scramble Circus and later appear in Conkdor Canyon from World 2, as well as Switchboard Falls in World 3.

Super Mario Odyssey
While Stingbies themselves do not appear in Super Mario Odyssey, mosquito-like variants known as Urban Stingbies do. They can be found in the Metro Kingdom during the night. When an Urban Stingby sees Mario, it charges at him, disappearing if it hits a wall.

Super Mario Maker 2
Stingbies appear as an enemy that can be placed in Super Mario Maker 2 stages, in the Super Mario 3D World style. Big Stingbies are generated by giving a Stingby a Super Mushroom.

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.

Captain Toad: Treasure Tracker
Stingbies return with the inclusion of Conkdor Canyon from Super Mario 3D World as a bonus stage in the Wii U version of Captain Toad: Treasure Tracker. Here, they behave just as they did in their previous Mario 3D platform game appearances, chasing the protagonist when they spot him and attempting to sting him. Captain Toad is able to defeat Stingbies with an airborne stomp or a well-timed spin. These enemies do not return in the Nintendo Switch and Nintendo 3DS versions since the level is not included in them.
