hi flyforum,

I was wondering what kind of fly this is.
A2-vein isn't good visible..

M1 seems to have a little wave (Muscidae?) and on the scutum there are some stripes?
Pattern on the abdomen is typical, but is it characteristic for Muscidae sp?

familyname is welcome but due to this picture perhabs to high level B)

picture from A.M. van Erkelens (Netherlands)

thx in advance,
Robert

Anthomyiidae.

...?:| , that's not what I expected..

What turns it Anthomyiidae?

Uh, a combination of many small features - call it intuition if you will :)

* The structure of the last segments of the abdomen
* Rather pointed with shape
* Rather long, thin legs
* Hind tibia with 2-3 long posterodorsals of equal length
* Arista almost bare
* Three postsututal dorsocentral setae

The abdomen is unusually distended. A fly after a huge meal - or a fly filled with parasitic fungal growth?

If I has the specimen, I would start looking in genus Delia - but there are other genera with rather similar flies.

Thank you Kahis for the nice supplement,
I'll see if I can learn these difference.
Without wing-characteristics I am mostly desperate lost.
And some species are more simple then others (Muscidae - Anthomyiidae)

And thank you for posting about Delia sp.
In the Netherlands are about 20 sp. of Delia but it's no use to look any further I think.
Anthomyiidae spec. and Delia with two question marks ;)
