How Much Do You Smell? #S02E02
Many insects and some mammals use smell as a primary means of communication. NOVA explains how, for example, the entire economy of an ant's nest is organized by smell, and how some moths use smell for population control—an ability we is now beginning to understand.
Episode 2 of Season 2 from NOVA — available to stream in HD on any device.
