Platanthera peramoena ​[pollination & insect interaction]

Notice in this picture both viscidium "tabs" have been removed from the anther sacs, but not enough to remove the pollinarium. Most likely from a    Spicebush Swallowtail Butterfly [Papilio troilus] or Hummingbird Clearwing Moth [Hemaris thysbe], known pollinators of Platanthera peramoena. Dauphin County, Pa. 8-3-20

 Unknown pollinator hairs stuck in the stigmatic fluid. Purple Fringeless Orchid [Platanthera peramoena].

Known pollinators of Purple Fringeless Orchid [Platanthera peramoena]. Spicebush Swallowtail Butterfly [Papilio troilus]. Dauphin County, Pa. 8-3-20. Hopefully its eye will come into contact with viscidium and when leaving will pull out the pollinarium. And when visiting the next flower the pollinia will bush against the stigma [the female part of the flower], the thus pollination will be achieved
