This spider was probably doomed - there were many small-headed fly eggs on the stick that the spider is resting on. But there were two small-headed flies in its web, so maybe the spider will have feasted on the cause of its demise.
About 100m of white flowered plants on roadside only (no plants at all away from roadside), probably a result of the grader. Some were twining through other plants but this one had nothing to climb on. It was GPSed but I uploaded unGPSed pics.
