Summary of the three hemocyte sub-populations’ characteristics.

Hemocyte sub-populations	Size (mean Ø)	Characteristics(structural complexity of cytoplasm)
Hyaline cells (HC)	10 µm	• Oval-shaped cells • High nucleus-to-cytoplasm ratio • Euchromatic centered nucleus • Very few granules
Semi-granular cells (SGC)	15 µm	• Low nucleus-to-cytoplasm ratio • Elongated cells • Large central nucleus • Well-developed organelles (rough endoplasmic reticulum) • Numerous granules
Granular cells (GC)	21 µm	• Very low nucleus-to-cytoplasm ratio • Spindle-shaped cells • Enclosed nucleus; finely dispersed nucleoplasm • Large, well developed, structureless lemon-like granules
