The Hornet and Electricity

This is a story to be found at www.physorg.com/print213449447.html, concerning the discovery that the 'oriental hornet' is able to convert energy from the Sun into electric power that in some way keeps it cool during the hottest period of midday. It can thus forage at the peak of the Sun's heat – and the conversion is done in the brown and yellow body parts. It is known that plants also have the ability to convert the Sun's energy into electrical energy – or are they picking up on an electrical element in the energy transmitted by the Sun?
