Hi Meigenia is a rather complicated genus as I see it and this one is unquestionably Meigenia sp. Therefore I need a helping hand. Following the Tschorsnig/Herting key for Central Europe the fly keys out nicely to M. uncinata. The genitalia seem to fit the drawings: Surstyli longer than cerci and both curved upwards. In combination with the pattern on the abdomen it should be Meigenia uncinata. Is this correct? At the time of the Central European key (1994) a find in Denmark of uncinata would be well outside the range of the species. Data: Length 7.3 mm. Captured 25. VIII 2008 on Pastinaca sativa in dry meadow in small deciduous forrest near Copenhagen. Walther Gritsch attached the following image:  [163.4Kb] |

Congratulations. No doubts here on Meigenia uncinata. In The Netherlands, it tends to be rare, southern or coastal. Theo |

Thank you, guys! I thought as much, but was reluctant to call it. This is then the first (presumably) documented find for Denmark The forrest is indeed very close to the coast. By the way... I caught two specimens on that day (both males). Regards Walther |

Uncinata has been bred from Chrysomelidae on Aparagus. Which is a coastal/dune plant. I don't claim this host to be exclusive, but it interesting, isn't it ? Theo |
