Orchid bugs?

I make no apologies for blipping bugs for the second day in a row. At least today's bugs are better lit as I'm not shooting in to the sun. I found these little critters on my orchid. They seem to be living at points where flowers connect to the stem. Anyone any idea what they are, if they'll harm the plant and how to get rid of them?

The pope was in Edinburgh today. I guess I should have made the effort to go out and watch him drive past but the thought of standing for hours in a crowd for a breif glimse didn't seem worth it.
