This is almost the size pencil in thickness. And why does it keep rubbing its front legs? Which is this?

If it is feeding on pollen or nectar, it is a tachinid fly - a beneficial insect. I don't know which one.

However, if it is feeding on filth, it is not.

I would say it belongs to the Family Sarcophagidae, and is possibly a Sarcophaga sp. but there are lots of them and nearly impossible to ID to species level.

Look at some examples in the Diptera Gallery under Navigation at top left.

Thanks both.
It is renown to have its filth diet. So I have to go for the searches suggested by wallaby. Yes, there are too many at our [at least me] level of knowledge to pin-point, but let's wait and see where we end.

Dinu, I have seen these on the Diptera site and I do know that no-one, not even an expert dipterist, will give a species. A microscopic examination can even prove difficult to ID these!

Oh is it, wallaby? I never imagined it was so very complicated! What could be the reason evoluting into so many different species esp. of this Dipteras? But I'll post a few of the flies I find here. So look out for those, anyway.

Same or different?

It looks much the same to me! Both look to be males (the eyes).
