Mean proportion of honeybee choices for angle dependent stimuli when presented against different alternative stimuli: an achromatic, gray target without angle dependent or independent color (learning test), flowers with patterns produced by angle dependent colors at different orientation and inclination positions against the same flowers without the angle dependent patterns (transfer test); and, flowers at different orientation and inclination angles without the corresponding angle dependent color patterns against stimuli showing the respective angle dependent patterns on an uniform background with the same color displayed by the petals. ***P < 0.001, **P < 0.01, NS non-significant at α=0.05.
