This is another strange Nematocera. From the distance it looks like a Limoniidae because of the body proportions, but from closer up it more resembles a female Chironomid midge with excessively long legs for that family.

I think this is also Chironomidae, even when it's looks a little bit weird!

With the way the legs are helt, it could be Chironomidae. It gives the impression of a midge that can 'walk on water'. Do you have an image at higher resolution? And in what kind of habitat was it found?

I have the original image, but it is slightly out of focus, so no more detail is really visible.

This was a Nematocera of high mountain area. Essentially I found it attracted to some light source at an elevation of around 1800m in early August in the Japanese Alps.

Well, to be honest, I just do not know. The fact that the head is so well visible, rather than partly hidden under the thorax is a strong argument agains Chironomidae. The first antennal segment seems to be swollen and that is usually an indicator that it is one of the groups with (semi-)aquatic larvae. Because of the shape of the head I am inclining towards the Ceratopogonidae (again) but I have no definite charcters for that.
Since this may well be a species adapted to boreoalpine conditions, it can be rather aberrant from the usual species of its family. I guess it will too much to ask if you collected it...

I do not collect specimens. I do not have the gear to study them, and also I burn more time on my web site that i rerally should. I am approaching 10.000 images, which is a lot, if one considers that the site is up since April.

I indend to buy a steromicroscope sometimes later...

Another old thread? I am now also inclined towards Chirnomidae. Any thoughts on this?

Chironomidae is my first impression.
