Hi there,
Every sunny day this summer I have had to run a gauntlet up and down my stairs, which are outdoor deck stairs, past two or three yellowjackets and one or two of these guys. At first, seeing them in flight, I thought they were black and white hornets but then I saw one landed and it rather looks like a huge fly with delta-shape wings. They buzz threateningly as they fly past. I’m wondering if they bite. I’m terrified to walk past them, but I found a very dead one on the pavement to photograph.

Dear Amanda,
While Yellowjackets defending a nest might be cause for concern, this Tiger Bee Fly,
Xenox tigrinus, is perfectly harmless.  See BugGuide for additional information.  This dead individual may have fallen prey to another impressive and scary but harmless fly, a Robber Fly.

Thank you very much!  I was afraid it was like a horsefly that bit me once, and I won’t forget that!
