Five types of haemocytes: prohaemocytes, plasmatocytes, granular haemocytes, spherule cells and phagocytes, have been distinguished on the basis of ultrastructural studies. Prohaemocytes are ovoid cells with a simple structural organization. Plasmatocytes are larger; their cytoplasm contains well-developed rough endoplasmic reticulum, numerous mitochondria and free ribosomes. Granular haemocytes are the most numerous of the blood cells, characterized by the presence of electron-dense granules. The cytoplasm of spherule cells contains many spherules made up of filamentous material of medium electron density. Rough endoplasmic reticulum, free ribosomes and mitochondria are also found in the cytoplasm. Phagocytes are the largest haemocytes. Their cytoplasm contains an abundance of lysosomes and myelin structures. In addition to haemocytes, cells intermediate between plasmatocytes and granular haemocytes have been observed, which indicates that the granular haemocytes are derived from plasmatocytes.
基于超微结构研究，已区分出五种血细胞：原血细胞、浆血细胞、颗粒血细胞、球血细胞和吞噬细胞。原血细胞是具有简单结构组织的卵形细胞。浆血细胞较大；其细胞质含有发育良好的粗面内质网、大量线粒体和游离核糖体。颗粒血细胞是血细胞中数量最多的，其特征是存在电子致密颗粒。球血细胞的细胞质含有许多由中等电子密度的丝状物质组成的球体。细胞质中还发现有粗面内质网、游离核糖体和线粒体。吞噬细胞是最大的血细胞。其细胞质含有大量溶酶体和髓鞘结构。除了血细胞外，还观察到了介于浆血细胞和颗粒血细胞之间的细胞，这表明颗粒血细胞源自浆血细胞。
