Hi, On July 13 my attention was caught by a minute light blue fly sitting in the infructescence of a sorrel (Rumex thyrsiflora). My autofocus camera was hardly able to detect it. Compare its size to the small black ants and the aphid in picture 1! In enlargement, I found it was bubble-blowing. At that time I was unaware of your extended discussion of that topic, so I did not pay attention to the fly's position towards the sun or not, but it was a fairly warm day. The fly moved around (posssibly disturbed by the photoflash) without losing the droplet. However, the surface tension of the fluid, certainly no pure water, should easily stabilize it. I wonder if there are any studies of the chemical composition of these bubbles? Anyway, I am much more interested in the name of the little fly - is it possible to find out the genus? Thanks in advance, Sundew |

Next attempt to attach the image (size and name were ok, can't imagine why it doesn't work.)
