[IMAGE 2 of 4, also see previous image] This Atta mexicana
worker continues the process of removing a section from a leaf. She is cutting in an upward direction using her left mandible as an anchor, as her right mandible slices through the thick material. This evergreen plant, 'Nanche de la costa' (Ziziphus sonorensis)
was the only plant with fresh green leaves in the immediate vicinity at this time of year.
