while #19 is A12 and bears the styli (sing. They undergo five substages known as instars before fully developing into adult grasshoppers; each instar is characterized by shedding of the cuticle skin and gradual growth of wings. It speeds growth by thermoregulation mechanisms including dark color and solar exposure positions, both allowed only because of chemical defense. and its characteristics and appendages follows.
