scent trail
Odor breadcrumb line
A scent trail is the invisible path of odor molecules left behind by an animal, person, or object as it moves through an environment.
Dogs follow scent trails when tracking, and ants lay chemical scent trails to guide others to food sources.
The term extends to any traceable sequence of clues: Investigators followed a scent trail of financial transactions.
