superworm beetles question

[supersonicgecko]

so i have had two small matte black superworm beetles, and about a week ago i got two pupae to hatch into two big red beetles. These two big ones have turned the same color as the smaller ones. does that mean that two are male and two are female? I keep them together on top of oatmeal and potato. So are they different sexes or what?
