A strikingly dimorphic species, in which the females apparently mimic females of certain Parides, and apparently fly “knowingly” of this protection (Parides feed on toxic aristolochia vines), but one still cringes when viewing the females of torquatus flying at ground leverl within the shade of the forest, seeking young sapplings of its rutacea food plant.  Most swallowtails of the genus Papilio lay eggs mugh higher up on leaves in full sunlight– young or mature . Very local in El Salvador, like several species known only from in and around the El Imposible Forest.
