Batch size: 35.7 ± 8.5 range: 10–100; (n = 14)

Realised fecundity: 83.3 ± 13.8 (range): 50–140

Note: Similarly, McFarland (1988) recorded 80 eggs from one female.

Incubation time (days) (n=12): 9.3 ± 0.8

Note: McFarland (1973) reported 5 to 8 days

Batch configuration and attachment: Loose.

Colour: Off­white, becoming pinkish­orange, then transparent on maturity (Fig. 611).

Size (mm): (n=15) L = 0.67 ± 0.01, W = 0.62 ± 0.01, T = 0.62 ± 0.01

Width/length: 0.91

No. of rows of cells in micropylar area: 3

Shape: Very broad, bluntly ovoid, anterior pole slightly truncated (Figs 611, 612 & 614).

Characteristics: Egg distinctly marked on all surfaces by quadrate, elongated, concave cells with moderately broad walls, double­ridged walls arranged in longitudinal rows (Figs 611, 614 & 615). Aeropyles elevated, openings very large (Figs 614–616), present on all surfaces (Fig. 614). Rosette cells, secondary cells in micropylar area recessed (Fig. 613). Chorion rough, densely blistered (Figs 615 & 616).
