Dear Members,

I am no expert on flies at all, but I do have pictures of a fly (don't know the species or genus) bubbling. It had been bubbling for quite some time, before we decided to make pictures of this behaviour. The pictures were taken on the 22nd of May from 12:54 to 12:59 and like I said the animal had been bubbling for some time already and at 13:00 it was still bubbling. The pictures were taken inside the house in a room with only one window, facing northwards. By the way: anyone any idea what fly this is?

Cheers,

Hans
