This creature was spotted on the deck of a home in Olathe, KS. I’ve never seen anything like it. Any idea what it is?

This is a predatory Giant Robber Fly in the genus Promachus, but we are unable to provide a definitive species name at this time. It is possible that it is Promachus vertebratus which is described on BugGuide as “Green eyes, sometimes with some red” and it is reported from Kansas. Of the genus BugGuide notes: “Large robber flies with tiger-stripe pattern on abdomen” and “prey: insects, often Hymenoptera” leading to the common name Bee Killer.
