Orange-legged swift Spider - female (Nyssus coloripes)

A fast moving attractive spider with black cephalothorax and abdomen, black and white banded hind legs and orange front legs. The body had white patterns along the sides, a median white line on the cephalothorax and broken white pattern along the midline of the abdomen.
Its behaviour and erratic movements are a mimicry of the pompilid wasp (spider hunters) - the orange legs move up and down like the orange antennae of the wasps.
This species is seen throughout mainland Australia and Tasmania.
