The caterpillar appears to be Cycnia inopinatus, a tiger moth (Lepidoptera: Erebidae; subfamily Arctiinae) with the rather common odd name of the unexpected cycnia. They feed exclusively on milkweed, especially arid land species. See for an image and for a very detailed report.

I am less certain on the crab spider, as I cannot see its dorsum, and there are members of at least three genera that can have a similar appearance. It likely was ‘put off’ by the caterpillar’s spiky armature...
