Abstract—In this paper, we describe a method for detecting and identifying honey bees under infrared light using data matrix code markers, specifically the ECC200 code. The identification of the bees allows to automatically monitor the individual departure and entry behavior of the honey bees. Material costs per stainless steel platelet as marker are estimated at 0.5Ct. Therefore the process is suitable for marking a large number of individual bees. The bees are individually provided with a data matrix code. During the motion of the bees from the center to the hive entrance, the marker is read using an infrared-sensitive camera and a corresponding infrared light source. As bees do not see infrared light, the monitoring is interference-free and does not affect the behavior of the bees. On live bees, the procedure was successfully tested. The results show that it is possible to reliably identify bees under infrared light and read the associated code.
