I believe it's a trait shared by all greenhoods. Off the top of my head I can't think of any other orchid species with a mechanism that responds to stimulus like that, but hammer the labellum of hammer orchids rocks back and forth as male flower wasps attempt to fly away and mate with the labellum (mistaken for the female). There are a couple of videos on YouTube showing the hammer orchid in action if you are curious about them.

Wow, that's interesting. Is this a common thing among orchid species?

The labellum is sensitive to vibrations and will flick up to force the pollinator against the pollinia as it tries to leave. You can see it in the first image. It's likely the labellum was triggered by a gust of wind or when you touched it. They are surprisingly sensitive.

It would be good if you could take this into protective custody, and rear it to get an adult moth, for confirmation or otherwise of the suggested identity.
