Fig. 2. The mean feeding rate across frequency and direction; the lines for
different direction treatments are labeled (H, horizontal;
V, vertical; L, looming). Feeding rates measured from moths
tracking flowers moving in the L axis (approach-recede) are
significantly lower than those for control flowers (ANOVA, Tukey's HSD
P<0.05), but there were no frequency effects when using a
multifactor ANOVA.
