The yellow and black from a few weeks ago is the Black-and-Yellow Argiope - very common in North America and also known as the writing spider because of the pattern in the middle that stabilizes the web. They've been known to capture and eat monarch butterflies, dragonflies, and cicadas, but mostly eat smaller flying insects. A couple of pictures of the one in my garden.
A female wolf spider settled in right next to my front door, complete with eggsac. That was mildly startling. No web for her, since Wolf Spiders are hunters rather than web weavers. A picture of her, closeup, with the eggsac.
