Ray's Thought for the Day - Bifora's Beetle Buddies

All righty then. Crumby and me are taking pictures of a bifora. We have staked out a bifora; the same bifora as depicted in a previous venue subtopic. So wondering what pollinates bifora we took a picture of these beetles, tracking along on the bifora. There are also some little flies on the bifora, but so far, those particular flies have not allowed us to take their picture.

Yes we are photographing the bifora Ray. This photograph reminds me that I should have kept up better, entomologically. I have only a vague sense of which families these two beetles belong to.
