Fig. 1. Apparatus. (A) Plan view of the apparatus. Bees entered the experimental
arena via a transparent tunnel that could be closed. Video cameras
(V) recorded activity at both the feeder and nest. (B) Plan view of the
feeding and nest areas during phase 1 (single context) and phase 2 (dual
context). During phase 1, three choices with three colors (green, blue,
orange) were present at the feeder area and only one, background colored hole
was present at the nest area. In phase 2, both feeder and nest had three
choices cued by three different colors (green, blue, orange).
