Update: According to this article, Natural enemies and insecticides that are detrimental to beneficial Syrphidae, a parasitized puparium can be identified early on by its dark, brassy or slightly greasy sheen and its different shape. Emergence takes a little longer than for flies from non-parasitized puparia. This is clearly the case with this one.
