Moved

 
Introduced species?
Is this a European wasp species laying eggs on a European moth that came to America along with the European plant the wasp is on?

 
Yes
Sharkey 2004 said both the host moth and the parasite are natives of Europe. The name isn't represented in the 1979 catalog, as Muesebeck had described it as a new Nearctic species in 1967, giving it the name metzneriae. There is no indication in the catalog that he thought the species to be invasive. Sharkey suppressed metzneriae as a synonym of malvacearum.
