Jorge, there are crossed interfrontal. Some Muscidae has it too, but usualy it means Anthomyiidae, as in this case.

yes , Nikita. But I saw the wing venation and anal vein 1 doesn't reach margin. There are very, very few anthomyiids with anal vein not touching the wing margin. |

1. Still I think it is Anthomyiidae 2. Once at 2-3 years it snows in Antalia. Today I'm 'lucky' to observe this rare weather. Fly beg do not disturb them so far...

Nikita had reason. With these photos I will show it must be anthomyiid.

It is definitely a female anthomyiid. I will make a quess (risky with photos) and say that it might be a Lasiomma species, because I can see in the excellent photos two anterior katepisternal setae, not common in Anthomyiidae. The rather distinct vittae on the scutum look like L. strigilatum Zett., which appears early in the year. In one photo I can see at the bottom of the right eye what could be fine pale hairs That's where the name Lasiomma comes from, though not all species have hairy eyes. |

yes. It is right this fly has pale hairs on eyes. I can see two posterior katepisternal strong bristles as well. |

This is what I ment when I said anthomyiids aren't that difficult. If we can not identify them, the fault lies with us, not the flies

 So true, Kahis!! So true! Now, anthomyiids will turn so, so easy. Only cecidomyiids and chironomids and some sarcophagids will remain in the hell families. |

Many apologies, I meant to say: Lasiomma seminitidum Zett. Actually L. seminitidum and strigilatum females are really very similar in general appearence, and the only reliable structural difference is that in seminitidum the ventral surface of the costa (vein C) below the anterior spicules is setulose, and strigilatum it is bare, except at extreme base. Your photo could be either based on the characters visible. The males are easier to identify (as usual) and have different genitalia |
