Thread subject: Diptera.info :: Morellia podagrica?

I photographed this fly in amstelveen, the Netherlands. It looks suspiciously like a reent addition to the Gallery, viz. Morellia podagrica. Am I correct, or are there look-a-likes? Size approx 5 mm. Habitat: 1 m high grass with lots of Hogweed.

Hi Cor.
Morellia is correct.
I can't see tubercul on t2, neither I'm not sure there isn't, so I'd say Morellia sp. Morellia is difficult genus even with collected fly. (My fly in Gallery collected after photo and then IDed under microscop.)

OK, I'll settle for that! Thanks.

When lightening the pictures, it appears that this fly has obviously only one intra-alar seta. Am I mistaken ? If not, that should indicate Pyrellia, in this case P. rapax ?
Nikita, what do you think of that ?

The tuft of hair on apex of f2 and general appearance is for Morellia, but I'm still puzzled by the lack of anterior ia. :|

Stephane, I don't think there is any doubts that it is Morellia with all pro-Morellia and contr-Pyrellia jizz. Size, strong dusting, ventral hairs on f1 ...
I don't like and try do not use if possible this 1/2 ia (no reason, just personal preference), so I don't know why only 1 ia. May be second was broken?

OK, I'll forget this matter of intra-alar. This suddenly troubled me when I saw the pictures.
However, I don't think they are broken, they are missing on both sides without any trace at base. I assume there must exist Morellia species with this combination...
Thanks for your explanations Nikita. ;)

On the contrary. I will check ia on my flies!

I have a Morellia (hortorum) at home. I watched it this morning : it has only the posterior ia ! This character is not mentioned in books. I think it is good to know anyway.
Sorry to have raised this thread.

Regards.

And I have just collected in Sochi two females of M.asetosa - 1ia each ;)
