Different types of hemocytes present in hemolymph of larva of Galleria mellonella and their main functions.

The Most Common Types of Hemocytes	Morphology and Functions	References
Prohemocytes	Small circular cells with large nucleus. Prohemocytes are not present in all types of insects and are considered progenitor cells.	[54,72,73]
Plasmatocytes	Most common in G. mellonella, possessing lysosomal enzymes in the cytoplasm, participate directly in phagocytosis and are also capsule-forming hemocytes.	[54,72,73,74]
Granulocytes	Small nucleus, and granules in the cytoplasm. Participate indirectly in phagocytosis and directly in the encapsulation process. Usually the most common hemocyte type.	[71,73]
Spherulocytes	Present in some insects, it has spherical inclusions. They transport and secrete cuticular components (as the 66 kDa peptide). Its function in insect immunity is not well understood.	[54,72]
Oenotocytes	Large and spherule cells. Are non-adhesive and no phagocytic cells and containphenoloxidase (PO) cascade components.	[54,59,72,73]
