Abstract:
Homing foragers of the honey bee (Apis mellifera carnica) were tested for discrimination of colour marks presen­ted to them at the hive entrance. At a low rate of natural il­lumination the bees were not able to distinguish the coloured (yellow, blue) marks from those with a corresponding gray. However, their general orientation was not disturbed. From this the conclusion is drawn that at low light intensities bees have an achromatic vision besides their known co­ lour vision at higher intensities.
