2n=56 (Moss, 1983). Also called Ophrys borealis (Moss, 1983). A nectary is in a furrow in the centre of the lower lip; bees, wasps or beetles lick the nectar and a drop of sticky fluid in the pollen bundle hardens pollen in place on the insect's head (Johnson et al., 1995). Another common name is "big ears" due to the two leaves on the stem (Johnson et al., 1995).
