Rosalia funebris
I live in Caldwell, Idaho and I found one of these bugs in my daughters swimming tub. I have lived here since 1996 and I never saw this kind of beetle here. Are they native to Idaho??

I found a dead Rosalia funebris in Ontario, California
Is this an unusual find for Southern California? I've never scene a Rosalia funebris in this area.

Nice find!
It is Rosalia funebris, the Banded Alder Borer.

B & W Stripped Bug
Sean, Thank you so much for clearing this up. Of course our property is covered in Alders but we haven't seen this bug before this week, and we have lived here about 7 yrs. So we were very pleased and excited to find him.
Again thanks
