Pattaya, not rare, on vegetation, especialy near ponds, 8-10mm.
In addition to identification one more question. Am I right that perpetual moving forelegs is the immitation of wasp antenae (at minimum very successful to make full of me several times)?

Temnostoma (Syrphidae) do use their fore legs to imitate wasp antennae

There is a photo of Temnostoma bombylans at

1. Thank you Guenter.
2. On the http://www.thaibu...0212fa.jpg
I also find "trade mark" my fly copy - Himenoptera, Ichneumonidae.
3. On same address is the photo of same fly, but still identified only till "stilt-legged fly".
4. Information about Oriental flies almost absent. I thinksomething usefull is on Japanes sites. May be Xespok could give such links?

Hi Nikita,

I would not be surprised if this would be also a Rainieria sp,

http://xespok.net...1000006986

but this family is quite homogenous as far as I know, and could easily form just one subfamily in a larger group containing Neriidae, Micropezidae, Megamerinidae and maybe a few others, which means that very similar flies could easily belong to different genera.

I helped the thaibug web owner to place hundreds of his images to families (mostly moths though), so many of the IDs on his page are maybe not 100% sure. He also did not have the time to correct all obvious misidentifications, since it is very time consuming for him, because his website is still entirely html based.

As for other oriental diptera sites, unfortunately there does not seem to be many around. I think my gallery is the largest by distance as far as the Japanese diptera are concerned with close to 2000 Diptera images. There are other people with large photo collections, possibly larger than mine, but these photos are not on the web. I know a few other web sites, but many of them are specialized for families. There is a very good one for Syrphidae and another very good one for Asilidae. And there is a Japanese Diptera forum, which is good, but obviously most of the post is in Japanese, and deals with Japanese species only.

Apart from Japanese web sites, all other oriental wildlife web sites venturing beyond vertebrates are really tough to find, especially if your are into less popular groups, like Diptera.

Hi Xespok.
1.Thank you.
2. I also came to Rainieria sp. as most probable answer. But the silence of our Masters force me to suspect that it may be not as easy.

Is it realy Dolichopus?

As for Nikita's point 3, the fly in the linked image is definitely not Dolichopus but belongs to the subfamily Sciapodinae. I'm not familiar enough with the many Oriental genera in this subfamily to even propose a genus name.
