On the scent of deception: warning smells, olfactory mimicry and the legacy of Miriam Rothschild
Deception is common in nature, with animals and plants masquerading as different species in order to mislead others. While warning colours are easily recognised, warning scents are far harder to measure, but despite this there are some tantalising indications that deception may be just as frequent in the olfactory realm.
