Period of oviposition: 19 Aug.–14 Oct. Batch size: 40.2 ± 7.2, (range): 5–85 (n = 16) Realised fecundity: 4–343 Note : McFarland (1988) reported a realized fecundity of 60 eggs from one female . Incubation time (days): 9–18. Batch configuration and attachment : Attached; singly, small groups (Fig. 415). Colour: Pale yellow, shiny, opalescent becoming pinkish orange then greyish­brown on maturity (Fig. 415). Size (mm): (n=16) L=0.86 ± 0.01, W=0.63 ± 0.01, T=0.54 ± 0.01 Width/length: 0.73 No. of females: 3 Aeropylar opening size (m) (n=7): L=2.38 ± 0.17, W=1.61 ± 0.09 Relative aeropylar opening size: 2.8 Micropyles : Indistinct No. of openings: 4 No. of cells in rosette: 9 No. of rows of cells in micropylar area: 4 Shape: Moderately broad, bluntly ovoid; anterior pole slightly truncated, polar profile elliptical; dorso­ventrally flattened (Figs 415, 416 & 418). Characteristics : Egg marked all over by hexagonal cells (Fig. 418). Cell walls generally moderately broad, elevated, floors flat (Figs 418–420); micropylar cell walls narrow (Fig. 417). Aeropyles prominent, elevated, with moderately large domes, openings moderately large (Figs 416 & 420); present on all surfaces apart from middle of top of egg (Fig. 419). Chorion moderately rough, due to moderately sparse granulations (Fig. 419).
