I was filming a damselfly laying eggs in my pond when I noticed this fly on one of the lily pads.
What was unusual was the way it was moving its proboscis side to side across the leaf just like a vacuum cleaner.
I have tried some searches in the hope of finding out what type of fly it is, but so far have found nothing which looks like this one. In size it was about 10 to 12mm in length which might explain why I did not even notice the other bugs on the leaf until I cropped and enlarged the photo. They would appear to be only 1 or 2mm in size.
With luck there may be some video of it on Friday along with the damselfly.
While I was looking for the above fly on the internet I did find what I think is an identification of the red eyed fly from a while ago.
I am now pretty sure it was a Flesh Fly from the group Sarcophagidae. I don't think it will take three guesses to work out what its diet is.
