Fig. 3. (A) Percentages of individual moths (sample replicates in parentheses) that approached only (grey bars) or approached and probed (black bars) at four different temporal manipulations of sensory stimuli in a wind tunnel (see Materials and methods and Table 2 for experimental and statistical details). Different letters denote significant differences between treatments for the probing variable. *Based on the response of two moths. (B) Median ± first and third quartiles of the time elapsed between take-off and approach to the visual target under different conditions of odor presentation (see Materials and methods and Table 2 for experimental and statistical details). Different letters denote significant differences between treatments for the `approach time' variable. Numbers in parentheses are moths that approached the visual target and thus are a subset of the sample sizes given in Fig. 3A.
