Hence, the nectar robbers apparently limited themselves to piercing holes only in the wall of the hypanthium, without harming anthers, stigmas, ovaries or
androgynophore. Two types of scars were identified: one of them made by flower piercers (76%), which consisted of two holes, one circular and one elongated, corresponding to the penetration of the hypanthium by the lower and upper part of the bill, respectively; the other corresponds to bumblebees (24%), with holes and sizes of various shapes, since these animals chew the surface of the nectary.
