While I haven't done an intense study of it, I very frequently see multiple bee species, natives and honey bees, on the same flowers. This includes things like raspberries, mint, dandelions, various fruit blossoms, as well as vegetables. I'm sure there is specialization in at least some of the natives, but some of them, the bumblebees especially (or maybe that's just because they are bigger and easier to see), seem to be pretty generalist foragers much like the honey bees
