.1 A novel technique for tracing the movements of insects in the field is described. 2 The detection system is based on radar technology originally developed for locating avalanche victims. The key of the system is a tiny electronic diode that, glued to the insect, can reflect microwave beams emitted by portable detection equipment. 3 The technique has been successfully tested in a field‐tracing experiment with carabid beetles. The results show that these insects are capable of dispersing surprisingly long distances in a relatively short period of time.
