Neomyia is correct, but this is the 2nd European species,
Neomyia viridescens. The two species are easily separated by the setae on the back of the fly:
Neomyia viridescens has four dorsocentral setae behind the suture,
cornicina has three.
viridescens lack presutural acrostichal setae; there are no long setae betwee the dorsocentral rows.
