Fig. 4. Pattern of nest-site scouts performing shorter and shorter dances over
consecutive returns to the swarm cluster. (A) Each line indicates the average
pattern of reduced dancing for scout bees that danced during one, two, three
or four consecutive returns to swarm. A total of 78 scout bees were observed,
and 51 performed dances: 24 danced during just one return to the swarm, 11
danced during two returns, eight danced during three returns, seven danced
during four returns, and one (not shown) danced during six returns. For an
example of a bee producing increasingly shorter dances over four consecutive
returns to the swarm, see the bee Orange (O) in
Fig. 2. (B) Summary plot of the
decay in dancing by nest-site scouts over consecutive returns to the swarm.
Each data point represents the mean of the values shown in A; error bars
represent ± 1 s.e.m. The overall rate of dance decay is –17.2
dance circuits per return to the swarm cluster.
