The Endermite Spawn Egg is a unique item used to instantly generate an Endermite, a tiny hostile creature. Players typically use this egg in Creative Mode, as it is not available in Survival Mode without cheats. When used on a block, it spawns an Endermite, which will attack players and can be used to lure Endermen, as they have a natural predisposition to attack Endermites.
This item has no numerical item ID, therefore you must use the item ID to spawn the item. Numerical item IDs were removed in Minecraft version 1.13.
