Cucullia xeranthemi Boisduval, 1840

D e s c r i p t i o n. Egg subspherical ( fig. 21 ), height 0.6–0.7 mm, diameter 0.7 mm (n = = 3). Fresh egg white. As egg develops, it becomes pale pink. Before caterpillar emergence egg becoming grey.

Chorion ridged, marked on two thirds surfaces. Micropylar area clearly expressed, represented by rosette and 3 rows short and broad cells ( fig. 22 ). Rosette and cells of first series have floors with clearly expressed long and narrow ledges ( fig. 23 ). Micropylar rosette elevated with 6–10 cells and 4 micropylar opening s ( fig. 24 ). There are 10–13 of 24– 25 clearly expressed longitudinal ridges radiate from tertiary cells ( fig. 25 ). Longest ridges with high comb especially in anterior portions ( fig. 26 ). Transverse walls less distinct and narrow than ridges. Aeropyles weakly expressed at walls junctions. The entire surface looks like of shallow network ( fig. 27 ).

Shape of gnawed holes in eggs. Caterpillar nibbles out large oval opening at lateral part of egg ( fig. 21 ).
