Oviposition period: 3 Oct.–7 Nov. 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 females: 2 Aeropylar opening size (m) (n=4): L = 7.4 ± 0.27, W = 4.07 ± 0.15. Relative aeropylar opening size: 8.4 Micropyles : Distinct (Figs 612 & 613) No. of openings: 4 No. of cells in rosette: 5 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).
