Sensory manipulations influence flies' preference for the tallest, steepest cone. Horizontal bar graphs show the percentage of the 10-min trial that each fly spent on each of the four cones and the arena floor (as in Fig. 4). Box plots show distribution of data after dividing by the surface area, which was identical for each cone. (A) Intact flies in the light (N=45). (B) Intact flies in complete darkness (N=45). (C) Flies with antennae immobilized in the light (N=40). (D) Flies with antennae immobilized in complete darkness (N=40). See Fig. 4 for description of statistical analysis and explanation of letter codes for homogenous groups. Crosses denote outliers.
