Batch size: 5–40 (n = 2) Realised fecundity: 45 Note: McFarland (1988) reported 211 eggs from one female . Incubation time (days): 10–11 Batch configuration and attachment : Attached, in large groups. Colour : Pale green, becoming pale pink with reddish­brown blotches to pale green with dark brown blotches (Fig. 235). Size (mm): (n=10) L =0.94 ± 0.01, W =0.71 ± 0.01, T=0.59 ± 0.01 Width/length: 0.75 No. of females: 1 Aeropylar opening size (m) (n=7): L=1.56 ± 0.08, W=1.36 ± 0.08 Relative aeropylar opening size: 1.7 Micropyles : Distinct (Figs 236 & 237) No. of openings: 6 No. of cells in rosette: 12 No. of rows of cells in micropylar area: 6 Shape: Moderately broad, sub­elliptical; anterior pole slightly truncated, polar profile sub­circular; dorso­ventrally flattened (Figs 235, 236, 238 & 239). Characteristics : Egg marked all over by sub­rectangular cells (Figs 236, 238 & 239) except only faintly discernible on posterior pole (Fig 238 & 240); loosely arranged in longitudinal rows (Figs 236, 238 & 239). Cell walls generally moderately broad, elevated (Figs 240 & 243), forming a mesh­like reticulum over egg (Figs 236, 238 & 239), floors flat (Figs 241–243); micropylar cell walls narrow, slightly elevated (Fig. 237). Aeropyles slightly elevated, openings small, present on anterior pole (Fig. 236), narrow lateral sides only (Fig. 242). Chorion smooth (Figs 241–243).
