Ok a lot of features fits Phytomyza gymnostoma, but some not: sutellum coloration, top of head coloration, the body size - this one at least 1 mm smaller, ....
mybe this is male, but speculating. Time of year & place of find is the same for both images on link, the upper is Phytomyza gymnostoma female:
