Chloridea virescens

Eggs are hemispherical with a flattened base, laid individually, initially white or light yellow, and measuring 514 µm to 530 µm in diameter and 528 µm to 540 µm in height ( Fig. 10A ). The micropyles, from four to six, are surrounded by rosettes with a variable number of primary cells, ranging from 12 to 20 ( Figs. 10A, 10B, and 10C ). In the lateral region, there are 10 to 13 primary and 10-12 secondary ribs. The primary ribs terminate at the top of the egg, closer to the micropylar region than the secondary ribs ( Fig. 10A ). Aeropyles (0.6 µm – 2.5 µm), from two to five, are present on the primary ribs, mainly close to the top region of the egg ( Figs. 10D and 10E ), but sometimes they are present on the secondary ribs. The surface of the egg has a stippled texture ( Fig. 10F ).
