Para-Biddybud

Para-Biddybuds are sub-species of Biddybuds first appearing in Super Mario 3D Land. They resemble multicoloured ladybugs with bird-like wings.

Super Mario 3D Land
Para-Biddybuds make their first appearance in Super Mario 3D Land, where they're found in groups and fly in circles or in lines. Some groups are seen one above the other or one after the other. Mario can defeat them with any attack, just like Goombas. They generally appear in groups of five, though there are some levels in which less then that number are shown together or they appear individually.

Super Mario 3D World
Para-Biddybuds reappear in Super Mario 3D World. They act the same as they do in Super Mario 3D Land, appearing in groups that roam in a set pattern. In this game, they can be seen in groups greater than 5 as well as less than 5.

Mario Party: Island Tour
Many Para-Biddybuds populate the Star-Crossed Skyway board in Mario Party: Island Tour. However, they do not affect gameplay.

Mario Kart 8
A kart designed after a Para-Biddybud will appear in Mario Kart 8.

Trivia

 * Para-Biddybuds bear minor resemblance to Soarin' Stus from Super Mario Sunshine.
