Agree with Eric...
There are several Trogus species that specialize on swallowtail larvae, so we will have to leave this at the genus level for now.

Yes.
Female ichneumon, likely the genus Trogus, among the very few ichneumons that are recognizable to genus from images alone. The great amount of detail on the host helped immensely as well.
