I find th spider on my front door last week, summer like temps, 75° F @ 7:45 am. It was about the size of a Kennedy Half Dollar, I got my neighbor to relocate it off my door.
The caterpillar I  found  outside at work about 2  years ago,  late August  early September,  moderate  summer temps.  It was too neat and pretty to not take a  picture of.
I don’t have any idea what kind either of them are.
