The video shows a close-up of a person's skin with a white, hairy caterpillar crawling on it. The caterpillar has a shiny, translucent body with visible hairs and is moving slowly across the skin. The skin appears to be slightly reddened around the area where the caterpillar is crawling. The video is shot in high definition, and the focus is on the caterpillar and the immediate area around it.
