Ant anatomy

The 3 main body regions of insects are the head, thorax, and abdomen. In ants, the abdomen is subdivided into the propodeum, which is attached to the thorax, and the metasoma, comprised of the waist (which in this case, is the petiole with one node) and the gaster (the enlarged portion that appears as the abdomen proper).
