Hi again, is it possible to identy this Geomyza and distinguish between hackmani and balachowskyi? Found on 13.05.2021 near Hannover, lower Saxony, germany. Thanks a lot. Best regards Alex |

Females of Geomyza hackmani normally have a largely black abdomen, not this banded patern, but I have seen exceptions to this rule. Also Geomyza hackmani normally has a much darker subscutellum. So this all seems to point in the directlon of Geomyza balachowskyi. To be entirely sure you would have to study sternite 8 which is retracted. Considering what is visible this is almost certainly a female of Geomyza balachowskyi. Jan Willem van Zuijlen |

Thank you very much, Jan Willem for the explanation and description of ID criteria. I hope to keep them in mind ;-) Best wishes Alex |
