This insect was spotted climbing slowly over an orchid (Speculantha sp.). Not sure if it could be a pollinator or just hanging around. (See sighting 4375475 for orchid)
Interesting it was crawling over the orchid but looks a bit too large to fit into the orchid and therefore not likely to be pollinator. From the little we know about these sort of greenhoods, they seem to be pollinated by tiny flies such as Phoridae and similar families.
