Yes folks we have a winner! 
Congratulations are due to LizDavies who correctly identified this weekend's teaser. 
Honourable mentions to Happy28 who got so very close to snagging three-in-a-row and to Kiki, Chassy, Munzly and everyone else who thought the image was something to do with snails.
I showed this image and asked what it was...
Liz said, "There's lichen on stone, with dead flies squashed in it, and snails circling round."
Well Liz, you were 99% correct! (no dead flies) 
Congratulations Liz, the virtual prize draw is now open. Also if you'd like a customised desktop of any of my images, let me know which one and your screen resolution and I'll be happy to provide it.
