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! Jonas |

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.

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.
