The Water Spider (Argyroneta aquatica) is a arachnid that is between 10-15mm long.

Our lakes have a big population of water spiders. These creatures make a bubble nest underwater. They breathe by carrying an air bubble down below the surface. They feed on other tiny creatures such as Phantom Midge Larvae.

Canterbury's water spiders are the subject of international research.

Water spiders are about 20mm long.
