We describe and compare the egg chorion of five species of three genera of Pierinae: Pieriballia, Itaballia, and Perrhybris. Their characterizations and illustrations include the main structural features: number and arrangement of longitudinal axes (short and long), and quantification of ribs or cells, projections and vestiges or reminiscent ribs. Also, we describe the color and size of the egg. We typify two egg models: elongated ellipsoidal or fusiform and oblong ellipsoidal, both with projections in the apical area, around the micropyle. Comparisons are made between features present in different species and genera. We discuss their phylogenetic and taxonomic implications.
