A bug, or insect, generally depicted as a caterpillar, which becomes a 🦋 Butterfly. Shown in full profile facing left, with its segmented, textured body arched upward as if inching along the ground. Typically green in color and often featuring black stripes or yellow dots as well as tentacles on its head.

May be used to represent various insects and creepy-crawlies. May also be used for metaphorical senses of bug, such as a software error, an annoyance (e.g. a "bugbear"), a hidden listening device, or an enthusiasm (e.g. “catching the travel bug").

Twitter’s bug is purple. Apple’s bug is hairy with a red head and legs and black stripes on its body. Facebook’s bug also has a yellowish-orange head. Google and Microsoft’s bugs previously resembled an orange centipede or millipede, and Samsung’s had a cartoon-styled face with a purple nose.

This emoji predates the inclusion of emojis within Unicode. It was first added to early Japanese emoji keyboards by SoftBank in 2000.

Bug was approved as part of Unicode 6.0 in 2010 and added to Emoji 1.0 in 2015.
