It is not Occam's razor but a reduction. We do not need to talk about macroparameters in thermodynamics because they can be explained by microparameters. So there are no pressure and temperature, only positions and kinetic energies of individual particles. "Eusociality" here is not an explanation of a phenomenon, it is not a cause of a phenomenon but a classification. Eusociality doesn't explain (at least in this particular case), it just a mark for the phenomenon to be a member of the wider class of phenomena. At the same time exposure to light, orientation relative to gravity, etc might explain observed eusociality, so they might be targets for Occam's razor.
