PLB: so far as I know, bees cannot follow individual bees.
According to Jürgen Tautz in "The Buzz about Bees: Biology of a Superorganism", under "Recruits, please follow the signals" (page 109): "Bees with and without local experience, at least when flying to a feeding site, form small mixed groups of up to ten individuals. Those with local experience land first, followed soon after by the inexperienced bees (Fig. 4.27). Tandem landings sometimes occur--the experienced bee below, and the inexperienced bee on top."
