2.5mm, Clitheroe UK, 9 October.
Is this
Scatella tenuicosta?

Hi,
I found some similar Ephydridae today - on a brackish pool, walking on water :-) (for belgians - op de spuikom)
Are there similar species?
Thank you!

Yes, there are a number of similar species - tenuicosta and stagnalis are the most frequently found on freshwater, but they both occur in brackish situations, along with paludum, subgutatta and others.

Thanks Tony,
could you advise me some literature for keying out the genus Scatella?
Or I post some pictures :-)

Hi,
I checked my pictures.. The bristles on thorax are different, and wing markings are darker :-)
So:
Crapy pic, I know ;)
BYe, Jonas

Currently the best work is Olafsson's paper - see
http://www.dipter...icle_id=18 under Ephydridae. I am preparing an account of the British fauna which will have a key to the North-West European species. It will take a bit of time as it includes what appears to be a new species from England.

And your photo is also
tenuicosta - some of the bristles on Stephen's specimen are not showing clearly.
