Honeybee radar tagging. Worker honeybee (Apis mellifera) being tagged with a radar transponder antenna. The bee (marked with a number) is gently held between tweezers. A tiny antenna will be adhered on to the bee's back and allow its flight path to be tracked in real time. The antenna weighs 12mg and measures 2cm. It does not need a battery and works by reflecting a component (harmonic) of an incoming radar signal. A portable radar tracking station is used to both transmit the signal and gather the information sent back. Photographed at the Rothamsted Research, UK.
