Agromyzidae, Phytomyzinae, probably a Cerodontha spec. female, which may belong to the C. (Poemyza) muscina group, in which 1/3 or 1/2 distal parts of the femora are yellow. Regrettably, the photo is outside the focus. The costa vein extents to the M1 vein and a hind cross vein is present (right wing in the left photo). Completely yellow femora of all legs are rare in species with dark thorax including dark scutellum. If a male or more specimens of this species are obtainable, the flies should be preserved for identification and description. C. (Poemyza) spp. attack cereals and other grasses. Please enlarge these photos with the information if the locality was North or South of 30° latitude as Zhejiang in its most northern part belongs to the Palaearctic, while most of the province belongs in the Oriental Region. Best add the exact locality with geographical coordinates (e.g. from Google Earth or Google Maps).
