Identifying the Black-and-Yellow Garden Spider (Argiope)

Q: A large black-and-yellow spider with a zipper-like web center is outside our front door. What is it?

A: It's an argiope, also called writing spider or zipper spider. Harmless except to small insects. If it's in the way, use a stick to wind up the web and relocate it to a less bothersome spot.
