Bombus species (Bumble Bee) pollinating Spiranthes cernua (Nodding Ladies'-tresses orchid)

A day trip to the Blue Ridge Parkway in North Carolina. I was lucky enough to find a nice bed of Spiranthes cernua beside the road. So, I stopped to photograph it and was soon joined by a Bee and a Butterfly. What a great day...

This Bumble Bee already has a load of pollinia on its proboscis before entering the orchid flower.
