On either side of the mouth opening there is a pair of multi-segmented maxillae along the mandible. It consists of two main parts. Cardo and Stypes. The base of the maxilla is called the cardo. The long and slender upper part of the cardo is called the stipe. Gallia and lacinia are present at the head of the stipe. Besides, there is a five-segmented maxillary pulp on the outer side of the stipes. Maxillary pulp is sensitive. The function of the maxilla is to pick food, catch food, feed food into the mouth and clean the front legs.
