Jerry, in your message of 2 July you mentioned that Howard Evans was the motivating force behind the development of a solar powered infra-red transmitter that can be carried by a bee. I saw it pictured several years ago, but a letter of inquiry was not answered. Do you know if the transmitter worked, and is it available?
