The eating behavior of ants as a sign of what is to be
Look up myrmomancy in Wiktionary, the free dictionary.
Myrmomancy (from Greek myrmex "ant" and manteia "prophecy") is the practice of reading omens from the observed behavior of ants, especially from their eating behavior. It is a form of entomomancy (from Greek entomon "insect"), which is itself theriomantic (from Greek therion "wild beast"; also known as "zoomancy"). People who use this divination technique subscribe to the worldview that the movements of ants are, in some supernatural way, ultimately connected with their life and that an understanding of these movements enables one to learn about the future. The interpretation of ant behavior may vary cross-culturally.
