Oviposition period: 18 Mar.–20 Apr. Batch size: 27.8 ± 5.4 range: 7–60; (n = 10) Realised fecundity (range): 15–163 Incubation time (days): 17–29 Batch configuration and attachment : Securely attached, singly (Fig. 617). Colour: Very pale green, becoming pale with small, sparse orange blotches (Fig. 617), then transparent on maturity. Size (mm): (n=10) L = 0.68 ± 0.01, W = 0.61 ± 0.01, T = 0.50 ± 0.01 Width/length: 0.90 No. of females: 3 Aeropylar opening size (m) (n=6): L = 2.13 ± 0.07, W = 1.72 ± 0.16. Relative aeropylar opening size: 3.4 Micropyles : Distinct (Figs 618 & 619) No. of openings: 4 No. of cells in rosette: 5 No. of rows of cells in micropylar area: 3 Shape: Sub­globular, anterior pole slightly truncated; slightly dorso­ventrally flattened (Figs 617, 618 & 620). Characteristics : Egg distinctly marked on all surfaces by hexagonal, slightly convex cells with narrow, recessed walls (Figs 618, 620 & 621). Aeropyles elevated, openings moderately large (Figs 618 & 619), present on all surfaces apart from wider, lateral side (Fig. 619 & 621). Cells in micropylar area slightly recessed. Chorion rough, wrinkled, coarser in micropylar area (Fig. 621).
