Yes Octhera mantis.Have only seen this fly once.On reeds at the
edge of Lough (Lake) Neagh here in Ireland. Although it is often figured in works on Diptera I have seen very few in collections.Nice photo of a nasty fly. See how it got it's name.

Than Ephydridae. Ochthera sp.
Thank you Gerard and Robert.
My test, the absence of sources about Orintal flies, makes the task to create photoguide even more interesting. This fly is collected, so may be Marina Krivosheina give me species name.
Nikita

Should have said cf. (means compare with or close to) mantis although definitely Octhera. Could be another species but it is exactly like mine but now I look also very like Ochthera anatolikos a U.S.A. species which is pictured on Diptera Info/ Weblinks /Image Galleries /Insects of Cedar Creek.Sleepy Robert

Checked a bit more The Bishop Museum Catalogue of Australasian and Oceanian Diptera (closer to you in SE Asia)http://hbs.bishopmuseum.org/aocat/aocathome.html
doesn't yet list Ephydridae:(. I'm sure they (Bishop Museum) would help if you can collect one. Raining here Robert

Yes, I know this site.
It seems that Ochthera isn't rare in Oriental.

Whoa wait wait, are you serious?!?!?:o
Octhera mantis is common all over Finland and it's found wherever there is surface water through the year. It especially loves peat bogs so I guess it may be a species of acidic soils and water. There's often a few (but seldom more)
mantis in the net after sweeping back and forth a few times over suitable wet surfaces. My yearly 'catch' must be in the thousands.
Our 2nd species,
O. manicata is very rare and has been collected only a few times from the ?land islands between Finland and Sweden.
