A driver was shocked after this bizarre 12-legged creature began crawling across his windscreen.

Native American Galen Metoxen thought the orange mass was a dead leaf when he noticed it in the Oneda Nation Reservation in Wisconsin last Friday (13/09).

He pulled over and began filming the hairy creature before yelling ''what the f*** is that thing? Anybody know?''.

Galen said he was surprised when he saw the "dead leaf" moving around his windshield. Despite growing up in the great outdoors, he did not recognise it and had never seen anything like that before.

He added: ''I'm a Native American from the Oneda Nation Reservation. That's where I shot the video.

''The creature was on my windshield. I thought it was just a crunched up dead leaf until I saw it move a little then I put it on the side of the bed of the truck

''I've never seen anything like this before.''

The bizarre-looking insect was actually the larva of a hag moth which is also called a 'monkey slug'.

The monkey slug is easily mistaken for the shed skin of a hairy spider or leaf debris. It has six pairs of curly projections, three long and three short from the flattened body, each densely covered in hairs.

Galen prodded the creature several times before setting it free on the roadside.
