Barrowbugs are small creatures native to Bajor that live in mounds.
The Bajoran resistance fighter Lupaza once compared a successful raid on a Cardassian base with "kicking over a mound of barrowbugs." (DS9: "Ties of Blood and Water")
- In the non-canon Star Trek: Terok Nor novel Day of the Vipers, they are compared to Earth cockroaches. However, they are about the size of a humanoid's fist and spit acidic venom.
