KIN AND FAMILY. “Examples abound, from a mother sheep distinguishing her lambs from others, a monogamous prairie vole (Microtus ochrogaster) recognizing its partner by smell, or, in many species, avoiding close kin when choosing a mate. Similarly, in social insects such as ants, bees, wasps, and termites, the differences in chemical profile between colonies allow animals to distinguish nest-mates and non-nest-mate conspecifics.”
