"In Scelionidae,
one extrinsic muscle of the antenna, the cranio-antennal muscle, originates from the frons. Both the precise
site of insertion and the function of this muscle are unknown, but it may be homologous with one of the
extrinsic muscles originating from the tentorium in other Hymenoptera."
