Hello! I have never seen such flies like this couple of only 7-8 mm long ones in our garden yesterday (Ostwestfalen/Germany). After searching a little bit I think, they could belong to genus Paragus. Is that correct? Thanks!

Hello, Amlia! amalia_raluca wrote: Eumerus sp. Ah, thanks! I had an Eumerus here in the garden already on May 28, but that lacked the distinct thorax stripes: Juergen Peters attached the following image:  [41.38Kb] Best regards, Jürgen -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Juergen Peters Borgholzhausen, Germany WWW: http://insektenfo... -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= |

if you look closely you can see has 2 stripes on the thorax too. the different angle makes them not that clear and in old specimens this dust stripes can become less clear too. |

for determination to species level you should examine the legs very carefully and maybe the male genitalia also. |

Yes, I have read that Eumerus cannot be determined after a photo (but that's all I have). There are 16 species here in Germany according to "Entomofauna Germanica".
