I wondered what "harmonic radar" was so
http://www.globaltechnoscan.com/28feb-5march/insects.html
gives a good short synopsis. In essence it is a "chip" attached to the
subject which acts like a transponder. Seems a lot like the transponders
used by aircraft to id their positions on radar. Nothing new as far as
the concept, but a lot smaller.
With the current state of such devices (for instance in inventory use
and also considered for library books) you could have a lot of data
attached to each bee so would not lose them even in a cluster. They can
be as small as threads. Interesting stuff.
