The hemocytes of the fifth instar nymphs of the grasshopper Melanoplus differentialis (Thomas) (Orthoptera: Acrididae) have been the subject of this study. The hemocytes of this insect, based on the fine structures of its cells, have been found to fall into four main categories or groups: Nucleocytes, Plasmatocytes, Granulocytes and Coagulocytes. The bases for their classification are differences in the ultrastructure of the cytoplasmic organelles as well as cytoplasmic inclusions are revealed as revealed by electron microscopy.
