Hello, This syrphid is from Black Sea coast in September 2010. I ask for (1) its identification, (2) meaning this behaviour. It presses with its forelegs the flower from both sides; as result of this, the pollens fall down. Is this behaviour known? What is the advantage for the fly? Comments are very much appreciated.

The fly is a Melanostoma. I have not heared of this behaviour before but I think the genus has pollen eaters so it might be a way to get some pollen out and eat it.
