One of several species (forms?) of small, metallic, torpedo-shaped beetles I have observed on flowers (mostly, I think, Viguera stenoloba, Skeleton-leaf Goldeneye) in the butterfly garden here at the WBC HQ. They seem like buprestids to be, and within that, most resemble the genus Acmaeodera. Any confirmation or further identification would be most welcome! Note, on this one, the intense red edge on the tips of the elytrae, which is less visible in this dark photo than in life.
