Abstract: Objective To study the responses of Cethosia biblis to color and odor in its foraging behavior. Method The attractive effect of C. biblis by different colors and volatile compounds were investigated respectively.Result It was found that both visual and olfactory signals had effects on the foraging behavior of C. biblis. Among five colors, C. biblis showed a clear preference to white (the proportion was 56.67%), followed by yellow (20.00%) and pink (15.00%). In light trapping test, the attractiveness of different color light at night was better than those in daytime generally; and the pink light attracted the largest number of butterfly (42.22%). Olfactory signals were significantly attractive to the adults of C. biblis. The models scented with 1% methyl salicylate (35.17%) and synthetic blends (1% α-pinene+1% methyl salicylate+1% 1-octanal) (32.42%) attracted significantly more adults than the odorless ones. Conclusion It is concluded that, both olfactory and visual cues play important roles in food searching behavior of C. biblis, while the adults depend primarily on olfactory signal to choose appropriate food. The butterflies obviously prefer to white flower, which possibly related to strong reflection of the white flower.
