Hi, St?phane L. helped me to identify this little fly and suggested Anthomyia imbrida, is anyone able to confirm it ? You can see a larger view by clicking the image below.  France : 19/4/2008 : 50km South of Paris - size : about 6mm ref:30774 Regards, Vin'S Edited by Vince on 20-04-2008 11:45 |

Not possible to separate Anthomyia imbrida and A. procellaris or bazini except by counting the number of anterodorsal setae on the hind tibia (males), 9-15 in imbrida, less in the others. Of course the genitalia are also different. The hind tibia in this photo are out of focus  |

Thank you very much for your answer. I thought we could see the apexes of the setae behind the tibia but I was wrong. Hard to identify an Anthomyia without catching it I guess  |

More recently Mike has said "One can separate most of the British species by the shape of the postsutural black lateral spot on scutum where it joins the wing base, or has a gap." (pers. comm. 9 May 2015) so presumably there is now sufficient evidence to support this being A. imbrida

Sorry for my probably wrong suggestion in 2008. I followed this part of Michael's key : 7 Posterior margin of the lateral postsutural black spot on scutum more or less straight just below level of the posterior intra-alar seta. Arista with longer hairs (longest slightly longer than the basal aristal thickness. Hind tibia with about 5–9 ad setae. sternite V in ventral view with shorter setae on inner margin of processes basally, outer lateral setae also shorter; in profile the ventral setae are continuous, and the angle between the narrower ventral membranous lobe and base is obtuse ..................................................procellaris Rond.and bazini Séguy - Posterior margin of the lateral postsutural black spot on scutum distinctly indented just below the posterior intra-alar seta. Arista with longest hairs equal to basal thickness of arista. Hind tibia with more numerous ad setae (generally from 9-15, occasionally more). sternite V in ventral view with the setae on inner margin of processes basally with longer uni- to biserial setae; in profile with wider membranous ventral lobe (somewhat square ended) and base forming a right angle with the sternite V process, and longer) lateral setae at base of processes......................................................................................................................................... imbrida Rond. As the lateral postsutural spot seems distinctly indented, and the arista seems virtually bare, I suggested it could be imbrida, but said it had to be confirmed by counting the ad on hind tibia. Stephane. |
