The mitotic apparatus in dividing cells of the ring-legged earwig is composed of the cell center or pole, chromosomal fibers, continuous fibers, and chromosomal and background structure. Parts from cellular elements such as Golgi membranes, endoplasmic reticulum, and nuclear envelope as well as whole mitochondria associate with the spindle microtubules to produce the diffraction pattern of the spindle fibers as seen with the light microscope. The microtubules of the chromosomal fibers attach independently and demonstrate the diffuse nature of the centromere or polycentric condition of the chromosomes.
