Egg of Cassida pfefferi

( Figs 11 – 13 , 18 – 21 ; Table 1)

Measurements (n=6). Length of egg: 1.10 – 1.20, width: 0.5 – 0.6 (Table 1).

Eggs are elongate-oval, yellowish-white. Eggs are deposited in oothecae which consist of translucent layers. Two to three eggs are usually deposited in one group (ootheca), but in the laboratory oothecae with a single egg were observed. Each egg is placed between two layers ( Figs 11 – 13 ). Surface of the translucent layers is without any distinct sculpture ( Figs 18 – 21 ). In nature on the top of ootheca a small piece of excreta is placed by female ( Figs 11, 12 ), in laboratory some ootheca were without excreta ( Fig. 13 ).
