I was outside on my balcony when I saw about eight of these things flying around then one landed on the building and I have no clue what it is.

Hi cori,
The Cottonwood Borer, Plectrodera scalator is usually described as white with black markings.  It is a beetle in the family Cerambycidae.
We really love the narrative mystery mood of your photo.  It is quite cinematic.

  1. I saw this bug on my apartment porch today, and it scared me to pieces! I had never seen it before and it reminded me of a very large cock-roach with much a much different color pattern! Can this bug be dangerous or poisonous at all? Thank you.
