I caught the spider in a plastic 35mm film canister and put it in the freezer overnight. Taking it out this morning and inverting the canister, it dangled a bit from a filament of webbing. Looking at this photo, it seems to have webbing stuck to its body - I guess a spider and its web are pretty inseparable.
This is a 123 image stack, taken with a Pentax K-3, D-FA 50mm macro lens reverse mounted on about 140 mm of extension, with dual manual flashes for illumination. The images were combined in Zerene Stacker.
