WATCH: Residents spooked by 20ft '˜web' spun by ermine moth caterpillars

The web, which covered a number of trees in the area, has been spotted by many people and has been identified as a caterpillar web.

The webs were spotted by Kate Arnold when she was on her way home from work in Luton, Beds..

Kate said: "When I drove past it I had to stop and have a look. Insects don't really creep me out and I was so intrigued to see this.

"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.
