Fly drinking water

[sleepo]

I'm not sure if the fly was blowing bubbles or drinking water... either way, it was a stroke of luck that I had my camera on hand!

Not convinced I managed to get him in focus, but before I could try again he flew away!

blowing a bubble - much debate about this habit but may aid digestion.

Good one- a bubble blower (well technically a drop blower).
