• Employing linearized Vlasov–Maxwell system of equations, the whistler instability is discussed for a semi-relativistic bi-Maxwellian distribution. The dispersion relations are analyzed analytically along with the graphical representation and the estimates of the growth rate and instability threshold condition are also presented in the limiting cases i.e., ξ±=(ω∓Ω)/k∥vt‖⩽1 (resonant case) and ξ±≫1 (non-resonant case). Further for field free case i.e., B0=0, the growth rates for Weibel instability in a semi-relativistic bi-Maxwellian plasma are presented for both the limiting cases. •Analysis of resonant and non-resonant whistler instability for semi-relativistic plasma is presented.•Resonant and non-resonant Weibel instabilities for semi-relativistic plasma are also discussed.•Physical motivations for our work are presented with its possible applications to laboratory, space and astrophysical plasmas.
