This species has the annular zone with clearly defined cells with smooth walls and interior, a wide transition zone with barely any sculpture and an equatorial area whose cells have prominent walls and tubercles forming a crown. S. spini (Denis & Schiffermüiller) ( Fig. 5 E, F) has prominent spiny tubercles protruding from the corners of the cells on the tubercleaeropyle zone, a not well defined transition zone and a depressed flat annular zone with circular holes and a lobed micropyle rosette normally with three primary cells. S. ilicis (Esper) , S. esculi (Hübner) , and S. acaciae (Fabricius) share very similar egg morphology, with spiny tubercles that are shorter in these three species than those of S. spini . S urrounding the annular zone S. ilicis ( Fig. 6 A, B) has a set of rounded tubercles which make the micropylar depression deeper and can be diagnostic from S. esculi ( Fig. 6 C, D), that is otherwise a very similar species. S. acaciae ( Fig. 6 E, F) has always scales glued to the chorion surface, because the female covers the egg after laying it with scales from a specific tuft located at the end of its abdomen. Finally, S. pruni ( Fig. 7 A, B) shows an annular zone almost devoid of ornaments. In the transition and tubercle-aeropyle zone it has a structure of quadrangular cells, whose edges give rise to small pinnacles with opened tips.
