FIGURES 13–16. Gymnetis pudibunda feeding on sap from adult and larval galleries of Megaplatypus mutatus ( Coleoptera : Platypodidae ) on the bole of Salix humboldtiana (Reserva Ecológica de Vicente López, Buenos Aires, Argentina ): Fig. 13, adult gallery (see the air bubbles located in the entrance of the gallery), together with Compsocerus violaceous ( Coleoptera : Cerambycidae ) (photograph by Lucas Damer, 17 December 2012); Fig. 14, larval gallery, 21 December 2012; Fig. 15, adult gallery together with ants (photograph by Rocío Gonzalez, 7 January 2012); Fig. 16, adult gallery together with G. chalcipes and C. violaceus , 2 January 2013. Note. A first male cone of Cycas revoluta , produced in the summer 2009–2010 , was visited by G. pudibunda alone. A second male cone, produced in the summer 2012–2013 , was visited only by Retrachydes thoracicus (Olivier, 1789) ( Coleoptera : Cerambycidae ), 16-I-2013 , one female (ODIC).
