Fig. 3. First choice of a color at the feeder for control experiment. Graph plots the proportion of bees (out of seven) that made the correct choice in each trial. The solid line represents bees that were trained to only a single context (feeder) and the dashed line represents bees trained to two contexts (feeder + hive) during phase 2. The last five trials of phase 1 (-5 to -1) and the first five trials of phase 2 (1-5) are shown. Solid gray line divides phase 1 and 2. ^*Indicates significant difference (see text for statistics).
