Pseudoips prasinana (Linnaeus, 1758)

D e s c r i p t i o n. Egg subspherical, flattened ( fig. 1, 2 ), height 0.6 mm, diameter 1.1– 1.25 mm (n = 2). Egg pale citron colour. As egg develops it becomes dark yellow with brownish-red spot at apical part of egg and same interrupted stripe on perimeter of its medial part. Before caterpillar emergence egg becomes wine red. Chorion white, translucent.

Рис. 1–6. Яйца Nolidae , Chloephorinae: 1–5 — Pseudoips prasinana . Яйца Erebidae , Hermeniinae: 6 — Pechipogo strigilata . Масштабные линейки: 1, 3, 6 — 100 мкм; 2, 5 — 1000 мкм; 4 — 10 мкм.

Chorion ridged, marked on two thirds surface. Micropylar area specific, sharply expressed, represented by rosette and 1 row of petalled cells ( fig. 3, 4 ). Rosette clearly expressed with 14–16 long and narrow petalled cells. Secondary cells with sharply expressed distal edges. Resulting micropylar area rounded by raised ring. There are 7–8 of the 32– 35 longitudinal ridges radiate from cells of micropylar area. Longest ridges slightly wavy, with high comb, especially at apical part of egg. Transverse walls less distinct and narrow than ridges ( fig. 5 ). Aeropyles clearly expressed. Chorion folded everywhere, especially in the area of micropylar rosette.

S h a p e o f g n a w e d h o l e s i n e g g s. Caterpillars nibble out large rounded opening at apical area of eggs.

O v i p o s i t i o n. Eggs laid in single-layer tight clusters where they pressed one to another.

R e m a r k. Egg shape, micropylar area and form of gnawed holes in eggs similar to those in some species of subfamilies Xyleninae ( Conistra rubiginea ) and Аcronictinae ( Dolinskaya, 2011, 2014).
