( In the case of " Pterostylis sanguinea ", the pollinator is a male fungus gnat of the genus " Mycomya " which attempts to copulate with the labellum, which produces the chemical attractant . ) The insect then enters the flower and either because it has passed a balance point, or because it has touched a sensitive part of the labellum, the labellum moves forward trapping the insect between the column wings, the labellum and other flower parts.
