From: The formation of a hatching line in the serosal cuticle confers multifaceted adaptive functions on the eggshell of a cicada

Fig. 6

Prior casting of the hatching line by serosal cells during early embryogenesis. Nuclei in the germ-band (GB) elongation stage (20 days after oviposition) were visualized by Feulgen staining. An image of the whole egg is displayed in the inset. The nuclei of serosal cells were distinctly gathered along the developing hatching line (arrowheads). Crossed arrows indicate the anterior (An) and dorsal (Do) directions
