Fig. 1.

a Mean number of dance followers (±s.e.) that followed at least one circuit of the first ten circuits of a focal dance, and b mean number of circuits of a focal dance that were followed by a dance follower (±s.e.) for dances performed in either multiple-patriline or single-patriline colonies. Dances were produced by foragers who were trained to visit a feeder in a greenhouse that held one of two concentrations of sucrose solution (1.0 or 2.0 M). Asterisks indicate significant differences between colony types, which were found consistently across sucrose solutions
