Redstone Bugs (Thermobia lapisrod) are a species of gigantic thermobians indigenous to the Overworld, now believed to be critically endangered or extinct. They are similar to the Giant Silverfish but are assumed to be more closely related to Firebrats due to redstone's likelihood to form near lava, meaning that they are likely very hot regions inside the Minecraft World.


The specific name, "lapisrod", comes from the Latin word for "stone", Lapis, combined with the Swedish word for "red", röd. This was chosen due to their association with redstone, and the fact that the creator of Minecraft, Notch is of Swedish origin.


Redstone Bugs infest redstone, indicating that they likely consume it. Electrical signals sent through redstone dust may stun or hypnotize them, but an error in the signal causes aggravation and will cause them to emerge and attack Modern-Day Humans.

Redstone Bugs live individually but have a defensive swarm mentality, and others of their species will respond to another of their kind being endangered and move to kill the offending creature. The Redstone Bugs make their possibly-infrasound cry after injury so talented adventurers can avoid the swarming by killing the organisms in a single hit.

Like Giant Silverfish, they are able to burrow and hide inside of stone and man-made cobblestone.


  • Redstone Bugs had the same appearance as a normal in-game Silverfish, but shaded red to match the color of the redstone that they spawn over.
    • They also utilized the same behavior as silverfish.
  • They spawned when a redstone error is activated, on the spot of the error.
