Found this fly in a birdbath in Ansbach, 2024-10-15, garden near old deciduous forest in Frankenhoehe Nature Park. The pattern of the mesonotum is distinct and the light patches above the lateral margins of the abdominal tergites are partly visible. Can it be Phortica semivirgo and is it a male or a female? Thanks a lot for your comments. EDIT: Phortica semivirgo confirmed by Jan Máca! eklans attached the following image:  [112.16Kb] Edited by eklans on 17-10-2024 11:48 |

I am rather for P. semivirgo, the darkening of tarsi is apparent in the first picture. |

The tarsal coloration proved to be a reliable character in great majority of specimens where I examined genitalia. I think that labelling of the pictures as "cf. semivirgo" would be appropriate. |

Thank you Jan, I've changed the title to "cf. semivirgo". But isn't the distinct pattern of the mesonotum a reliable character, too? Greetings, Eric Kloeckner |
