Figure 1 in Flower perianth: first observations on a novel diet item for the ponerine ant Odontomachus chelifer (Latreille)

Figure 1 Three distinct moments of the interaction between Odontomachus chelifer ants and the nectar-producing flower of Neomarica candida (Iridaceae) in the sandy coastal plain forest (restinga) of the Cardoso Island State Park, São Paulo State, Brazil: (A) Two ants attempting to tear up one of the inner tepals; (B) One ant pulling a partially teared tepal; and (C) one ant carrying the teared N. candida tepal piece to the nest. At (B), we indicate how tepals (inner/outer) were divided based on their different colors in two parts (basal/apical) for performing the two-choice tests: IB (inner tepal, basal part), IA (inner tepal, apical part), OB (outer tepal, basal part), and OA (outer tepal, apical part). The arrow indicates the location of some nectar-secreting trichomes.
