My son found this at a local park and wants to know what kind of bug it is?

Cropped and linked...
Welcome to BugGuide!

I cropped and linked your images.

Cropping your images allows more of the insect and less of the background to be seen. Only the poster and editors can click on an image to get the full sized image. All other viewers can only see the image as it is above. Having the image cropped makes the insect more visible to them.

Pictures of the same insect can/should be linked. It helps find all of the images of an individual insect. Your first image was identified and moved to the guide page. The second images was still in ID Request.

I hope this isn't coming off as too harsh. I am in no way "beating you up" and truly hope it isn't sounding that way. I have been working all night and I just got home.

Please feel free to ask for help with the site if you need any. There are a lot of people willing to help. I am looking forward to seeing more of your pictures!

And again...

Welcome to BugGuide!

I think it is
Synaphaeta guexi, the Spotted Tree Borer, a Longhorned Beetle.

Thank you for taking the time
Thank you for taking the time to reply. My son is very happy to have a name to go with the bug. I have never seen anything like it before.

Congrats to your son for
finding a great beetle and to you for taking very nice photos!

The interesting thing about t
The interesting thing about this beetle is that the southern California populations are darker and smaller, while those in the Sierra Nevadas are larger and more silvery-white.
