PIXABAY When bumblebees land on a surface, they leave behind a smelly substance that other bees can detect, according to a study published yesterday (March 7) in Scientific Reports.
This substance, which is made of hydrocarbons, usually helps the bees cling to the surface of flowers. “Bumblebees secrete a substance whenever they touch their feet to a surface, much like us leaving fingerprints on whatever we touch,” Richard Pearce, a study co-author and biologist at the University of Bristol, said in a statement.
