It's a Scaeva. They are indeed big and loud. The experts should be able to give it a species name. Im too lazy to look it up, but there are just 2 possible names really (selenitica or dignota).

Thank you Kahis!

Compared with the pics in gallery: is it selenitica ? (the dark hairs on the top of the head in front of the eyes?)

It is S. selenitica - compare the discussion here: http://diptera.in...;pid=49852. The yellow marks of S. dignota crossing the abdomen edge are well seen here: http://syrphidae....c/sd4.html.
