Figure 3: 3D representation topographical measurement by atomic force microscopy of the cuticle around the acidopore of an ant of the Camponotus Formicinae species. A layered structure of the cuticle is clearly visible in the cuticle platelets surrounding the pore. The high aspect ratio of the cuticle exceeds the dynamic range of the instrument (gray).
