Electripede

The Electripede is a caterpillar-like scarab beetle that inches forward as it moves and can crawl on floors, walls, and even ceilings. When touched or struck, it stops in place and temporarily electrifies itself in self-defense, inadvertently illuminating the surrounding area with light.

In Pikmin: Decayed Leaf
The Electripede is a species of Scarab beetle in Pikmin: Decayed Leaf. The creature resembles its original counterpart in Hey! Pikmin. Electripedes are not hostile, but they can still shock Pikmin and kill them if touched. Yellow Pikmin are best to use when touching these bugs. Electripedes will crawl slowly on the side of walls or on floors; usually in very dark areas. If a Yellow Pikmin is thrown at it, the bug will react by creating an electric barrier. The barrier can kill Pikmin; but it also dimly illuminates the room it is in and lighting up Bloominous Stemples. Despite being hit; Electripedes do not take any damage.
