Cuckoo Wasp? Halictid? - Osmia - Male
Cuesta Ridge, San Luis Obispo County, California, USA
May 30, 2004
Would love to know what this is. If it's a bee, I guess it's a male (from the minimal hind leg hair). It was on Sidalcea hickmanii, along a ridgetop at ~2500 ft.

Thanks John...
...for getting me on track. It does look similar to this post . Shall I move it to the Osmiini page? (Trying to learn from Hartmut's examples :-)
