We see this but a lot in our garden here in San Marino California., which is right next to Pasadena, CA. We would love to know what it is. Thank you!
We suspect you must have milkweed in your garden. This is a Large Milkweed Bug, Oncopeltus fasciatus, and it will feed on the seeds of milkweed, but otherwise does not harm the plant. See BugGuide for more information on the Large Milkweed Bug.
