Your letter to the bugman : What IS this? After looking through some images, some characteristics are similar to hover flies, but it was so big! Bigger than a bee or yellow jacket, so I’d guess bigger than hover flies. It’s antennae were so short! It was just in the house near the sliding glass door. In the city but walking distance to rural areas.

This is most certainly a Fly and we believe it is a predatory Robber Fly in the family Asilidae. It looks not unlike this Robber Fly from Washington posted to BugGuide. One of the most unique features on your individual is the light orange color on the underside of the abdomen, but this is not a feature that is commonly seen in images posted online.
