Fig. 4. (A) First choice made by single M. sexta flying in a wind tunnel
(N=33). Different proportions are statistically significant (binomial
test; P<0.0001). (B) Stimuli visited by single M. sexta
within a 5 min foraging bout in the wind tunnel (unrewarded flower model)
(N=33). Mean number of visits ± s.e.m.: visual
target=3.41±0.49; odor source=1.62±0.16
(F1,43=5.60, P=0.023; ANOVA with square root
transformation).
