UPDATE (and response):
thank you very much lesinlondon. i search like half an hour on the internet but i didn't find the species.

i don't know exactly if i didn't shoot this picture at F2.8. i know i shoot some pictures in that session even at 2.8 but i don't remember exactly which.

i shoot 3 pictures of this fly in this position. all where in focus but only this one was focus exactly on the insect eye.

SPECIES INFO (wikipedia):
Yellow Dung Fly (Scatophaga stercoraria)
The adults are mostly predators on smaller insects - mostly other diptera, they will also feed on pollen, but most specimens seen on flowers will be hunting prey there. Both males and females are found on dung, the males only feeding on other insects that visit dung, such as blow-flies. Females will be there both to feed and oviposit on the dung surface,

Females prefer to lay their eggs on the small hills of the dung surface and avoid depressions and pointed parts of the dung. This ensures survival, as emergence is better by avoiding the drying on small points in the dung. Also by avoiding possible drowning by rain by not laying eggs in depressions of the dung surface. The female Yellow Dung-fly capable of making these decisions about her egg placement, and thus increasing possibility of success of her future generations. The eggs hatch into predatory larvae and feed on insect larvae within the dung. After 21 days or more of feeding, dependent on conditions, the larvae burrow into the soil around and beneath the dung and then develop into pupae, before developing into adult flies.

Scathophaga stercoraria can produce four or five generations per season. The adults are active throughout much of the year in most moderate climates. In most cases both males and females will mate multiple times, as is very common in insects. Much has been studied about the competition between genders and what factors determine mating success, and what part that in turn may play on the competitive nature on the larvae.
====================================================
I usually post more older pictures. This is a recent one. I shoot this last week when i was in vacation in Zarnesti (a mountain zone from Romania).

I shoot this in poor light conditions. This was shoot in a shadow of a forest at 17PM. So i had to use ISO800 and an open aperture. I had no flash or tripod.
The manual focus is really hard when trying to shoot macros with M42 lenses because you lose luminosity in viewfinder when close the aperture. Also the 400D viewfinder is low quality (small size, bad fresnel)

A Yellow Dung Fly (Scatophaga stercoraria). Gold colour for male, greenish tinge for female, this maybe a female. One of my favourite species. F4,critical focus, which you have accomplished very well with this subject. Very nice. tfp - Les.

The partial focus on the fly is very sharp and crisp, Anghel. With extension tubes, you have succeeded in getting a wonderful macro image of the sunject.
The colours too are fantastic.
Well done and TFS.
