Hadn't been aware of him at all while snapping away at the bud, sure, saw the ant, how could you miss an ant playing at 'king of the castle', but the spider? Nope.
I later found he came from a very fine web down amoungst the leaves.
And that small Hibiscus bud? well its full of all this........
Hibiscus flowers go in for pollen production in a major way.
