A beautiful bee photographed on Seaside Daisy (Erigeron glaucus) on Bodega Head, 23 July 2012. I was taken by the mint green eyes and the noticeable white hairs, giving the bee an extremely pale and fuzzy appearance!
I'll check in with a few bee experts to see if we can identify this species. If you're familiar with local bees and have some thoughts about this individual, I'd be grateful for any information. Could it be a type of long-horned bee? [Addendum 26 July 2012: Yes! Robbin Thorp confirmed that this is a male long-horned bee, Melissodes pallidisignata.]
