A dad got a shock when he found a very hungry caterpillar in his McDonalds - taking bites out of his Big Tasty burger.

Darren Bailey was left scratching his head after noticing the tiny green bug wriggling around on top of his burger bun - taking nibbles out of his dinner.

The 27-year-old had ordered a delivery from his local McDonalds in Bromley, south London, with his pregnant wife and their child when he noticed the cheeky caterpillar munching on his 460 calorie burger.
