(I've seen _bird & animal watching and behaviour_ is listed among the accepted topics.)

The question is maybe borderline, but I haven't found another stackexchange site for it. Please, feel free to move it if you know of one.

  - What type of insect is this?
  - Is it dangerous to bees? I've seen them feeding on flowers, but I've also noticed that, on the same plant, when they're there the bees are not, and viceversa.

The photo is taken in southern Italy.

It looks a lot like wasp to me, and in any case the colouring seems very peculiar, so I guess someone will know the answer.
