“…Another recent electronic-tag alternative, with energy harvested from the insect's wing beats has been developed. This still has a somewhat heavy and complicated payload for the insect to carry (Shearwood et al, 2017), and has a range similar to the method described in this paper. A final interesting result is the use of LIDAR to track untagged bees (Bender et al, 2003) although this requires a very carefully prepared site and doesn't allow individual targets to be tracked.…”

1. Current methods for direct tracking of individual bee movement behaviour have several limitations. In particular, the weight and size of some types of electronic tag may limit their use to larger species. Radars and other electronic systems are also often large and very expensive to deploy. A tool is needed that complements these electronic-tag methods. In particular one that is simple to use, low-cost, can have a high spatial resolution and can be used with smaller insects.2. This paper presents a candidate method that uses retroreflective tags. These are detected using a camera with a global electronic shutter, with which we take photos with and without a flash, the tags can be detected by comparing these two photos. The small retroreflective tags are simple and light-weight, allowing many bees to be tagged at almost no cost and with little effect on their behaviour.3. We demonstrate this retroreflector-based tracking system (RTS) with a series of simple experiments: Training and validation with a manually positioned tag; Case studies of individual bees; Tracking multiple bees as they forage in a garden; Use of real-time monitoring to allow easy re-observation to enable a simple floral preference experiment; and a very brief experiment with 3D path reconstruction (integrating two devices). We found we could detect bees to a range of about 35m with the current configuration. 4. We envisage the system will be used in future to increase detection rates in mark-re-observation studies; provide 3D flight path analysis; and for automated long-term monitoring. In summary, this novel tracking method has advantages that complement those of electronic-tag tracking which we believe will lead to new applications and areas of research.

“…Multiple limitations have been outlined, which restricts applying the technology to smaller-bodied insects, with the lightest commercially available tags available weighing > 0.2g [2][3], whilst the average weight of a honey-bee is 0.11g. A novel solution is proposed whereby the need for a battery is obviated by harvesting the bees' own energy enabling the use of a much lighter device [4]. The battery is replaced by a piezoelectric energy harvester capable of converting mechanical energy from the bee's thorax into electrical energy.…”

A novel approach for real-time monitoring of honey-bees across their natural habitat is presented herein. We present a wearable device which scavenges energy from the bee's mechanical vibrations to power the transmission of location data while ensuring minimal physical hindrance. The geo-physical location of honey-bees is determined by implementing a compact and low weight scanning system that can be used with a stationary receiver or coupled to a movable receiver for tracking across the entire foraging range. This is achieved through the combination and synchronization of a RF detector, steerable microstrip array and a microcontroller to estimate angle of arrival using received signal strength indicator (RSSI). The present approach addresses the fundamental limitations of current telemetry systems in terms of cost and adverse size/weight impact over the bee foraging behavior.
