The Blue-striped Nettle Grub (Parasa lepida, Family: Limacodidae) is also called Slug Caterpillar because of the way it moves.
Instead of prolegs it has a broad, black adhesive sole. The grub sticks to the surface by vacuum, pressing the sides of the belly down and raising the centre (Barlow, 1982). Movement is slug-like.
