Karl von Frisch and other bee researchers have observed that individual honey bees vary in their efficiency in packing pollen into the pollen basket; some are more efficient, others less.
The tremble dance was first described by Karl von Frisch in the 1920s (who was also first to describe the waggle dance), but no light was shed on its function until 1993 when Wolfgang Kirschner discovered that, when performed, the dance stopped nearby workers from flying to gather more nectar.
