I do not know the exact name of the plant, it was Asteraceae with yellow flowers. Maybe it was Hieracium umbellatum or something similar.
If your plant ID is correct, this is likely
Phytomyza. It is not
Liriomyza (bright yellow and black species) or
Ophiomyia (different subfamily). The genus
Chromatomyia is now considered a synonym of
Phytomyza.
