Hi Bugman!
This is a giant crazy wasp that I found in a mist net while banding birds. It was in some coastal scrub habitat in Marin County, California on November 5, 2008. I have no idea what kind of wasp it is.

Hi Walker,
This is a Wood Wasp or Horntail, and despite its “nasty” appearance, it is perfectly harmless and cannot sting.  We believe this is Urocerus californicus based on images posted to BugGuide.
