Sun-lit spider web under a garden table

I took this in my garden this evening. The web is underneath my patio table - I spotted it from my front room because the sun was catching it. I had 2 dogs trying to lick my face as I crouched under the table so it's a miracle it's in focus! The spider was absent...wonder where it is?

Camera/lens settings: ISO 100, f/5.3, 1/125s, 46mm, hand held.
