I have no idea what this bug is. It was so intriguing, however, I took about 40 pictures of it! I think it’s a beetle, since it can fly and its wings are hidden under a hard shell. It had black and white stripes.
Please identify this bug!

Banded Alder Borer

Your insect is a Banded Alder Borer, Rosalia funebris, which is sometimes called a California Laurel Borer, but according to Charles Hogue in Insects of the Los Angeles Basin “it does not use California laurel (Umbellaria species) as a primary host.”  According to BugGuide, the  “Larvae feed in dead hardwood trees: maple, alder, oak, willow, etc.”  Some borer beetles attack living trees, but this is not the case with the Banded Alder Borer.
