A drop of liquor leads to its death?

If you put a drop of liquor on a scorpion, it will instantly go mad and sting itself to death.

[from 2007 snopes.com article, no longer online]

A tiny amount of liquor on a scorpion will make it instantly go mad and sting itself to death. Probably not - but somebody who has one has a pet can test this! The venom won't do it harm but the stinger itself might (some scorpions have larger stingers than others). The notion of a scorpion stinging itself to death is an ancient allegory - surrounded by fire or by enemies a scorpion will sting itself to death rather than surrender. "Falsehood is a scorpion that will sting itself to death." -- Percy Bysshe Shelley

UNTRUE -- The belief that scorpions commit suicide by stinging themselves to death when surrounded by fire is of considerable antiquity and is often prevalent where these animals exist. It is nevertheless untrue since the venom has no effect on the scorpion itself, nor on any member of the same species (unless the venom is injected directly into the scorpion's nerve ganglion—quite an unlikely event outside of the laboratory). The misconception may derive from the fact that scorpions are poikilotherms (cold-blooded): when exposed to intense heat their metabolic processes malfunction. This causes the scorpion to spasm wildly and this spasming may appear as if the scorpion is stinging itself. It is also untrue that alcohol will cause scorpions to sting themselves to death.
