Top notch, John! Having done macro (more in the past than today), I know how immensely difficult this photo would have been to make. Well-executed!
Much obliged, Terry, and I appreciate the empathy on the difficulty
Most extreme macro stacks are done on dead arthropods ... it is especially difficult to deep stack live ones, as often they won't "hold still" long enough to allow for adequate DOF.
Crab spiders (and, often, Lynx spiders) rely on camouflage, so they can be stacked as live subjects and are interesting enough visually to be worth the effort
Cheers,
