Argyrodes antipodiana — a kleptoparasitic spider

These tiny spiders, commonly called dewdrop spiders (for an obvious reason), are just 3–4 mm long and live in the webs of other spiders, usually Eriophora pustulosa, where they steal prey from the host spider's web. This one was on its way to retrieve a  sciarid (dark-winged fungus gnat), which might have been too small to alert the host spider to its presence.

Takes the crumbs, as it were. Tidies up.

Zhoen, apparently they've been known to snack on the host, too.
