Nisista sp. 3 (Figs 435–441)

Oviposition 2♀ Code no.: G386, G391. Period of oviposition: 17–26 Oct. Batch size: 9–50. (n = 3) Realised fecundity: 9–90. Incubation time (days): 11 Batch configuration and attachment: Attached; singly, small groups (Fig.435). Colour: Pale green, opalescent, becoming deep purplish orange then greyish­brown on maturity (Fig. 435). Size (mm): (n=14) L=0.84 ± 0.01, W=0.62 ± 0.01, T =0.49 ± 0.00 Width/length: 0.73 No. of females: 2 Aeropylar opening size (m) (n=5): L=1.78 ± 0.23, W=1.41 ± 0.21 Relative aeropylar opening size: 2.3 Micropyles: Distinct (Figs 436 & 437) No. of openings: obscure No. of cells in rosette: 6 No. of rows of cells in micropylar area: 4

Characteristics: Egg marked all over by hexagonal cells (Figs 436, 438, 439 & 440). Cell walls generally moderately broad, elevated, floors flat (Figs 438–440); micropylar cell walls narrow, elevated; micropylar cells slightly recessed (Fig. 437). Aeropyles elevated, domed, openings small; present on all surfaces apart from middle of top of egg (Fig. 440).
