Figure 1

Plan view of the choice apparatus. The central arena for the choosing female consisted of a central neutral zone with an opaque plastic cylinder in the middle and four preference zones, which are separated from the central zone by dotted lines. The four tanks for the stimulus males contained the males' nests (N) and were placed perpendicular to the choice chambers. Solid lines represent opaque plastic walls whereas dashed lines represent UV transparent Plexiglas panes. Optical filters were placed horizontally over the four stimulus tanks.
