Figure 3. Two-choice experiments examining the visual and olfactory floral preferences of naïve male M. sexta moths in response to live flowers or scented bagged flowers.

(Top) The percentage of moths that chose the live D. wrightii flower (Flower A) or a bagged D. wrightii flower with D. wrightii scent (Flower B). (Bottom) The percentage of moths that chose the live A. palmeri umbel (Flower A) or a bagged umbel with scent (Flower B). 20 moths were used in each two-choice experiment. In both experimental series, there were no significant differences in the first flower chosen (G-test: P>0.71). D. wrightii flower cues (odor and visual) are represented by white bars, A. palmeri flower cues (odor and visual) are represented by grey bars, and hashed bars represent the real flowers.
