Hello,
This was inside on 7th January, near Lincoln UK. It was small, I think 5-6mm. It looks to me like
Heteromyza but the eyes are different to
H. atricornis male. Could this be
Heteromyza oculata? There are no photos to be found, I did find a female which looks very much like the one I had in December ..

Hi Janet
Your fly is a female. In most groups of flies, the males have bigger eyes, and are thus closer together. It's often one of the easiest ways to sex a fly (but there are exceptions!)

Hi Tony... uuhh, no I don't think this is a female, if it is then it has to be another species. ;)
Look at the eyes on the female I posted before ...

There's no 'head' showing at all under the eyes ..

Female's eyes .. loads of space between them on the face too!

I borrowed Roger's photo from the gallery to show the male's eyes of his H. atricornis ..

Agreed - it is male. I'll leave it to Andrzej to resolve!

I enclosed a pic from Czerny (1927) ! It is the head of the true male of
H. rotundicornis

Then it has to be
H. rotundicornis Andrzej! I think the drawing has over exaggerated the closeness of the eyes, there are 'grooves' on the face which may have been included in the eyes but really should not have been! I have photos of the same fly from January and early March last year, I posted it but I don't think I got a reply.
The only other
Heteromyza is
H. oculata which has "eyes tapered near ocelli markedly".
Is there a possibility the female I had could also be
H. rotundicornis?
Two shots of the head from last year .. this from 3rd March

Hi Andrzej, have you managed to compare your collection yet?
Assuming it is
Heteromyza then it should be
H. rotundicornis. Unless it is a different genus of course! ;)
It would be a nice addition to the gallery!
(p.s. I got another one on the window recently! :D)
