I read of "molecule of the month" bombykol http://www.chm.bris.ac.uk/motm/bombykol/bombykolh.htm
It struck me that the forces between molecules are not well understood. The force is just a distance dependency on a energy potential. Higher orders of electromagnetic energy potentials should be investigated. And I am not sure about the antenna design. It looks like electrodynamic effects of it. I would ask for someone investigate the molecular spectrum of bombykol and see if it coincides with the harmonic frequencies of the moth antenna. Something similar to Casimir forces could be the effect on the molecule. Casimir forces should be understood as something limiting the electrodynamical spectrum making the energy varying and thus act as force on the molecule. Casimir effect is not only active for ZPE but for any radiation. For some other insect they proved that they could detect a chemical even when it was too scarce in concentration to reach the antenna. This could be explained as either a radio detection, or, which is plausible since the receptors are dependent on physical presence of a molecule, that the antenna attracts the molecules.
