The trends in the magnetodielectric response fall into three clear temperature regimes corresponding to known magnetic and structural transitions. Above 65\\,K, weak magnetic field dependence of the dielectric constant is observed with no hysteresis. When 30\\,K\\,$\\leq\\,T\\,\\leq$\\,65\\,K, a strong dependence of the dielectric constant on the magnetic field is observed and hysteresis develops resulting in so called butterfly loops. Below 30\\,K, magnetodielectric hysteresis is enhanced.
