The strangest foragers

I recently had the pleasure of hearing Dr Chris O'Toole speak of his enterprise -- a low-tech spinout from Oxford University -- that aims to increase agricultural pollination through the introduction of solitary bees (much more of that soon).

But, meanwhile, he did introduce his talk by speaking of the huge numbers of solitary bees, few of which produce honey and some of them foraging off the most peculiar things -- like jaguar vomit.
