"It's so surreal, I have never seen anything like it before, when I got out the car I expected a 20ft spider like the one out of Harry Potter to be there.
"At first I thought it would be spiders, but when I went to have a look I realised that it was caterpillars.
"I have had a look on Google and realised that there aren't many sightings of webs this big in the UK which is really strange.
