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.

Congratulations.

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

Congratulations - and some nice photos there - would look good in the gallery :)

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 ?
