Would you believe I actually missed this first time around?
After looking at the footage on the Sky site I'd say it's definitly a spider (or possibly some other creepy crawly) going over/past the lens. See this YouTube clip created using ladybugs (ladybirds) http://www.youtube.com/watch?v=9OhjYOhhMPc
The Echo really went to town on the reportage there though didn't they?
