Regal Fritillary

There are many, many introduced parasites of Lepidoptera in North America. I
assume there is probably a list or lists somewhere that itemizes them. It is
unlikely that any exotic parasite would specialize in Regal Fritillaries,
but if the Fritillaries inhabit the same area as a common Lepidoptera which
supports a large number of generalist parasites, Regal Fritillaries could
have a high parasite load as an incidental side effect. All of which is
shear speculation of course.
