Oviposition period: 2–22 Dec. Batch size: 22.6 ± 4.3 range: 4–60 (n = 19) Mean fecundity: 42.9 ± 8.4 (range: 4–90) Incubation time (days) (n=14): 11.1 ± 0.6 Batch configuration and attachment : Loose. Colour: Very pale green, becoming darker at poles, then pink with darker streaks, transparent on maturity (Fig. 16). Size (mm): (n=15) L = 0.81 ± 0.01, W = 0.60 ± 0.00, T = 0.50 ± 0.01 Width/length: 0.75 No. of females: 3 Aeropylar opening size (m) (n=4): L = 0.31 ± 0.05, W = 0.27 ± 0.02. Relative aeropylar opening size: 0.4 Micropyles : Distinct (Figs 17 & 18) No. of openings: 4 No. of cells in rosette: 5 No. of rows of cells in micropylar area: 4 Shape: Moderately broad, bluntly ovoid, truncated anterior pole, dorso­ventrally flattened; anterior pole slightly angled to horizontal axis (Figs 16, 17 & 19). Characteristics : Egg marked on all surfaces by hexagonal, flat cells, cell form on wider top side, barely discernible (Figs 19–21), micropylar cell walls narrow, shallowly reticulated (Figs 17 & 18). Aeropyles very inconspicuous, very small, openings extremely small, present on all surfaces (Fig. 21). Rosette, secondary cells recessed (Figs 17 & 18). Chorion smooth, undulating (Fig. 21).
