It is safe to say that this is a Gorytes (4 spp. occur in MA, usually impossible to ID from an image). The little thing on the wing is definitely a stamen but not from an orchid. Orchid pollinaria are larger and firmly attached to the insect (almost always to the head). I have have seen many Gorytes (here in Ontario) but never with pollinaria. On the other hand some male yellowjackets (Dolichovespula spp.) carry them relatively often where the right orchid spp. are present (see this example from the Vespid Atlas (1). The object seen on this Gorytes is probably just a randomly broken-off stamen from a previously visited flower.

The white thing is likely to be a Pollinia (modified stamen) of an Orchidaceae flower. Here in Europe, some species of genus Ophrys have co-evolved with some Gorytini. Males attempt so-called "pseudo-copulations" and get one of several polliniae on their back. When landing on another flower, this latter will retain the pollinia, ensuring cross-fecundation.
