Is it known if the larvae of this fly form mines in Hogweed leaves?
I believe it does mine Hogweed leaves, along with quite a wide range of other plant hosts, see:
Entomologist and biological recorder
would that be hogweed, giant hogweed or both, as we have masses of each here?

If you look at the reference Martin gave, it uses all sorts of umbellifers. In this country, it suggests only sphondylium, but mantegazzianum is listed from the Netherlands.
