Hello,
this Agromyzidae was observed in our garden on september 17th. With these yellowish femurs and yellow antennae, I beleive that it could be Phytomyza rufipes. Are you in agreement with this identification ? All my thanks for a reply. With my best wishes, Jean-Michel Garel.

Phytomyza rufipes Meigen, 1830 (Agromyzidae), an ubiquistic and abundant leafminer fly, which exclusively develops in Brassicaceae (12 host genera are documented). The yellowish antenna, yellowish lateral stripe from shoulder to wing base and all yellowish femora together with a deep gena, complete matt scutum with few weak acrostichal setulae distinguish it from other Phytomyza spp. All Brassica crops including rape are attacked. During high-pressure weather the species in tremendous numbers undertakes dipersion flight. It is attracted by yellow colours and on fire-ships on the North Sea (positioned 56 km offshore) they were captured only by the yellow pan traps during long time trials with differently coloured dishes filled with 4% formaldehyd (von Tschirnhaus 1981: Spixiana Supplement 6: p. 53,71,105). The species also occurs in the Afrotropic, Nearctic and Neotropic Regions. I even found it in the Patagonian steppes. At least 384 collected publications deal with this species, the following six synonyms not counted: bistrigata Strobl, 1906; brassicae Hardy, 1853; femoralis Brischke, 1880; genislatissimis Strobl, 1803; ruficornis Zetterstedt, 1848; sulphuriceps Meigen, 1830.
