Sphegina is a genus that looks like it's intermediate between Baccha and Neoascia. But separation of the species is not easy.
Many thanks Howard, that looks very promising, and will be my first encounter with the Milichiidae! I'll key it out properly when I get a chance, but Madiza pachymera also looks like a possibility, judging by Nigel Jones's photo here (which was also from a flight interception trap):

Ken Smith's (yellow) book has a comprehensive list of references (albeit concentrating on the British Fauna).
The other book you should try to get is Aquatic Insects of North Europe, volume 2 - which is mostly Diptera. (editor Anders Nilsson). Again it has extensive lists of references at the end of each family chapter.
Hi - I think this is Terellia tussilaginis - but would be grateful if someone could confirm (I am not sure it there are any very similar species).
Insect was on Burdock near the River Stour in Merley, Dorset yesterday.
many thanks
Nick
I think that looks OK for tussilaginis; at least the other species that are found on burdock look a bit different
Hi Martin. Like Phil, I have joined in the hope that I can get some help with marine shoreline flies ID. I have logged in OK but I too am getting a message saying "You are not allowed to post new content on the forum". Any suggestions? Many thanks
This does indeed key out as Madiza pachymera - thanks again Howard for putting me on the right track.
Hi,
I have just joined this forum in the hope of finding a bit more about Diptera in general. I look forward to some helpful advice primarily with hoverflies but also flies in marine environments.
I live in Winchester but do get around quite a bit.

I can't see a photo. Took me a while to figure it out, but you need to upload the the image and then once uploaded, click the 'insert' button to insert the image into a comment - otherwise it won't appear in the comment.
Looks fine for a male inflata
