Net-casting Spider - female (Deinopis subrufa)
A slender long-legged spider with a couple of lateral knobs on the dorsal side of the abdomen. Spotted at night with a blue rectangular net which was loosely slung from the front legs. The spider was prepared to get its meal at this stage.
A wonderful experience for me - seeing the blue net was something special ! This species weaves a fine blue net of cribellate silk which is a dry adhesive silk. When an insect such as an ant comes into view, the net is quickly stretched and the spider casts it over the prey trapping it for food. The spider hunts at night, constructing its web late in the day. It might eat its web in the morning.
