It would probably be safe to say that most species of wasps will visit flowers when nectar and or pollen are available. Scoliidae wasps like this one make use of the sugar energy to find mates or search out potential prey/hosts. This group of wasps - there are many related species - are mostly parasites of underground beetle grubs. The parasitic stage of the wasp is a worm-like larva.
