Grasshoppers do not have an amniotic sac. Animals with amniotic sacs are mammals and birds that have a sac for the fetus to grow and gain nourishment from.
The protective sac surrounding the embryo is formed by the amniotic membrane and the amniotic fluid which together create the amniotic sac. This sac serves to cushion and protect the developing embryo during pregnancy.
