Figure 1


Fig. 1. (A) Line drawing showing the dorsal (mirror) view of a moth feeding from the robotic flower. All axes of motion are defined relative to the moth's perspective. The two axes illustrated are the horizontal axis (H), the moth's left and right, and the looming axis (L), approach-recede. The vertical axis (V, dotted line), is coming out of the page and is up-down for the moth. (B) A schematic showing how we determined the feeding time used for calculating feeding rates. The thick black line shows distance between the moth's head and the base of the flower (MFD). The broken line across the graph represents the maximum distance from the flower at which the moth's proboscis could contact nectar (calculated based on average proboscis length of the colony). Feed time was defined as (the last time MFD < broken line) - (the first time MFD < broken line). The feeding rates were calculated as (amount of nectar consumed)/(feed time).
