There is a good picture of this species showing the round dark spot at the posterior end of the scutellum, just anterior to the scutellum. Both sexes have this character

Here is a link. I don't know if it will work ?   Time to find out  !!

Thank you for the useful information. Looking at  Hybotidae in the Diptera.info website, it looks like Hybus sp. and perhaps Hybus culiciformis (with a question mark of course).

Why do you feel it's not Heteromyza oculata?

It looks like we still have some problems with the upload and display of images - sorry Bill! Will get this fixed as soon as we can.

Thanks, Tony, a good point. It was 'obviously' not H. oculata because it was obviously not the same as my two reference specimens - about twice the size for starters. However one of my reference specimens is probably H. commixta/rotundicornis, and the other is teneral, and both are females. There is still the problem that it has no frontal bristles, and should, according to the test key, have at least one. However I've seen one image on-line with a narrow frons and no frontal bristles. It looks as though it is H. oculata then!

Thanks again for coming to my help - not for the first time!

Thank you for putting me out of my misery! Of course it fits perfectly. It appears to be E. halidayi, with a distinct arista, pale stigma, small dark bristles beneath the hind femur towards the tip, and the thoracic pubescence and some of the thoracic bristles yellowish.

That's the last one of my Diptera problems sorted.. just a few other Orders to go. Very much appreciated.

That looks right to me.

Thank you

I'd love the record details for the Heleomyzid Recording Scheme please.

Perhaps Clusiidae

In the current version of the UK Diptera checklist there is no mention of Myopites apicatus. iRecord uses names from the UK Species Inventory, which currently gives Myopites apicatus as a synonym of Myopites inulaedyssentericae.

Laurence Clemons is the expert in this group, and in his 2020 recording scheme update he says "Controversy exists as to whether the species which forms capitulum galls in Pulicaria dysenterica (L.) Bernh. (Magnoliidae, Asteraceae) is Myopites inulaedyssentericae Blot, 1827 or Myopites apicatus (Freidberg, 1980)."

So my suggestion would be to record it as Myopites inulaedyssentericae but to add a comment with the record to say that it was on Fleabane, so that if a species split does occur in future the record can be correctly allocated.

Martin Drake has kindly provided some information on this one - it is "definitely a dolichopodid - there are few small metallic green flies outside chloropids (the others are big - strats and the like). Your fly is very likely to be Micromorphus at that size, and the straight long veins, greyish thoracic dorsum, wide tapering face and very wide frons, and flat prescutellar depression all point in that direction."

Martin tells me that there are believed to be three species in this genus in the UK but the taxonomy is not yet confirmed.

Photos associated with this post seem to have disappeared.  Anyone know why?

Thanks Michael, having looked at this picture I can see clearly that my specimens are indeed hilaris.

I have lots of other Anthomyiidae specimens to attempt to determine, the keys posted in the members area might make it possible to determine at least some of these!

John and Barbara Ismay have helpfully suggested that this fly may belong to the genus Leiomyza.  Indeed it does: L. scatophagina.  The wings must be deformed! Rob

Looks like a Phronia species but I would need to see the genitalia in ventral view to say which.

Tachina grossa 

Hi Becca - Where are the photos posted?
