Endermite

Endermites are small arthropod hostile mobs that attack by biting. They have a 5% chance to spawn when a player throws an ender pearl. Endermen are hostile toward endermites.

Endermites have a 5% chance to spawn when a player-thrown ender pearl lands. They spawn at the player's original position when the pearl lands‌[Java Edition only], or at the pearl's landing site‌[Bedrock Edition only].

An endermite despawns within 2 minutes, regardless of the player's distance, unless it has been named with a name tag. This applies even when it is in a minecart, boat, or boat with chest.
