This morning I found this little fly on my window.
I think it is Tachinidae.

What kind of Tachinidae is this?
size 5-8mm

Is it Phryxe nemea ?

Hi Robert,

You are way off. It is a Sarcophagidae: Oebalia minuta, formerly known as rufitarsis. Larvae in wasp nests in twigs of Sambucus and the like. Possibly flowers inside your house ?

Thank you Theo,

I now see there is no 'gevorkte steel' in the wingvain, that what is so typical for Tachinidae. I thought I saw this T in the wing but it is not a real T.

Long time ago I visited Diptera.info |t

I don't follow you, Robert.

It is not possible to separate Sarcophagidae from Tachinidae by wing venation (though there are some rules of thumb). And I do not understand what fork you are referring to.

I think I 've to search my diptera-book and find out what the hard difference are between sarcophagidae and Tachinidae.

I thougt the CuA1 wingvain of Tachinidae didn't reach the wingedge?

So I have to look for better rules to seperate these flies :S

Yes, you do. This feature varies at a generic level.
