Hello! A small (about 5 mm) nightly fly from our garden (Ostwestfalen/Germany). Anthonmyiidae or Muscidae? Somewhat similar seems to be the Thricops nigrifrons in the gallery.

If was obliged to give some answer, I would say that white mesotonum is some artefact and it is "nice little Fannia??" Nikita Nikita Vikhrev - Zool Museum of Moscow University |

But I don't think the white is a (photographic) artifact. It's not the first time I saw these little flies with the whitish (dusted?) thorax.

I suggest that the white on the thorax is pollen, and I think Anthomyiidae, rather than Fannia - the fly's right wing appears to have an anal vein clearly running to the wing margin.

Thanks! I had not taken pollen into account because auf the white colour and the regular, parallel shape. Had rather thought of some fungus.

Just at the moment, almost all the flower-visiting insects in my garden are covered in white pollen from Impatiens glandulifera (Himalayan Balsam), but I agree that the white distribution on the thorax is odd - it doesn't look like a fungal infestation to me, nor do I think it is a natural colouration. (A strange little mystery!  )

The mystery is solved. Today I collected 2 females of same fly. Tony was right - Anthomyiidae Eutrichota Mine is most probably Eutrichota socculata

Is that a (newer?) synonym of Parapegomyia socculata? Yes, it is. I use Ackland's key as main sourse of information, Ackland use Eutrichota. Also in old key for Europen Russia it is in genus Pegomyza. Nikita Nikita Vikhrev - Zool Museum of Moscow University |

Michael Ackland Eutrichota sp, perhaps schineri Schnabl Thank you Michael, I checked the specimen again - really, "arista with longer hairs, total width of hairing more than width of first flagellomere" Nikita Nikita Vikhrev - Zool Museum of Moscow University |
