Netcasting spider (Deinopis subrufa)

This spider was found in our garden just after dusk and it would not be distracted from it's purpose of waiting until an ant walked under it's web. The web silk is bluish and incredibly stretchy.
They also have amazing eyes with the lowest F number in the animal world.
They also grow a special light-sensitive membrane inside their eyes each evening and resorb it each morning.
The net is held just above a plain surface upon which they have placed two bright white spots to aid prey and motion assessment.
