Any idea for either the moth or spider?

Hi again Brett,
We haven’t a clue about the moth, but the spider is a Crab Spider in the family Thomisidae. Crab Spiders don’t build webs, and many species sit camouflaged in flowers awaiting pollinating insects.

Hi Daniel:
I can’t resist a twofer. The photo provides only a partial underside view of the moth, which looks like a Geometrid to me. Unfortunately, from the perspective of providing an identification, West Cape Province has over a 100 species of Geometridae and South Africa as a whole apparently has over 1000 species, most of them dressed in cryptic grays and sepias. The spider is indeed in the Thomisidae family, likely a flower crab spider in the genus Thomisus , of which there are at least 15 to choose from. The closest match I could find was T. citrinellus . Regards.
