The present study was undertaken to investigate the hematopoiesis of the hematopoietic organ found in orthopteran Euprepocnemis shirakii under both light and transmission electron microscopy. It was shown that the hemocyte differentiation of E. shirakii was distinct from features compared to patterns previously reported in other insect species: Their prohemocytes, plasmatocytes, granulocytes I, granulocytes II and spherulocytes were all derived from the hematopoietic stem cells surrounded by reticular cells. This pattern of hematopoiesis was also first observed in the Orthoptera. Thus, findings of this study strongly suggested that the patterns of hematopoiesis in insects differed, among groups, showing the need of an extensive investigation in order to correctly comprehend the patterns of hemocyte differentiation in insects in accordance with first order, and then systematically important taxa.
