I don't think that this is the case. But as there is much biological activity in the soil of Cypripedium habitats and as Cyps need fungi for their germination and later on as a protection against phytopathogenic fungi (not necessarily for nutrition!) I would assume that fungus gnats are quite common in these areas.
Best wishes for your work
