So I am designing a fantasy world, and in it are some fairly stereotypical dwarves, anyhow I was wondering is I could replace the traditional "canary in a coal mine" trick with a cricket and/or multiple crickets. This would give me the bonus of explaining why the dwarves hold them almost sacred as the help against the Blackdamp (underground gas). They would also be kept for music. So would this work? And if not, any other ideas?
EDIT: Sorry, should have been more specific, I mean any of the "Damps" be it blackdamp, whitedamp or firedamp.
