I took pictures of this Stratiomyidae fly on a Medicago sativa leave and thought first it was a Chloromyia, but after I compared the antenna color with similar featured genus (Chloromyia, Sargus, Microchrysa) and seemetd to fit with Microchrysa cyaneiventris, which is not known at FEu in Spanish mainland. Is that correct? [Iberian peninsula: Catalonia: Girona: Beuda, 400 masl, 2015 may 22th] rafael_carbonell attached the following image: [49.56Kb] Edited by rafael_carbonell on 23-09-2016 15:39 |

I'd favour polita.

Thanks Paul, but, has M.polita got a partly orange antenna? Looking at the web pictures it seems not, and in the case of M. cyaneiventris is yes. |

Well, Microchrysa polita has dark antennae... However, the shape of all Microchrysa antennae is different, they are shorter and more roundish, whereas here they are really elongated. I suppose this is another genus! What about Chloromyia speciosa (compare several pictures here: http://xespok.net...9.jpg.html)?

Eyes are haired so that should indeed ruleout Microchrysa. Brownish third antennal segment supports speciosa but the colour of basitarsi 2 and 3 does not strike me as 'contracting yellow'...

Yes, the colour of the legs was darkened by the shadow. In another picture I can see clearly basitarse III is yellow. And the pictures of "xespok" of C. speciosa are the first I see with partly brown antenna. Thanks to all |
