About Anthocharis gruneri Herrich-Schäffer, 1851
Description from Seitz: The nominate A. gruneri H.-Sch., found in Greece, Southern Turkey, and Asia Minor, is smaller than cardamines but otherwise similar. Males of this form have broader black apical markings, and the ground color of the wing upperside is strongly yellowish. The form armeniaca Christ., native to Asia Minor and Mesopotamia, has a more whitish upperside, and its orange-red apical patch has a dark proximal edge. The form ab. homogena is an intermediate between these two. The form diluta nov. [Röber] flies near Angora, and is distinguished by less developed greenish markings on the underside of the hindwing. Additionally, female diluta have a dark forewing apex that is almost completely lacking markings. In Syria, where the species does not appear to be plentiful, a distinct special form occurs: it is small, with a pure white upperside and a reduced orange patch that only reaches the black median spot, and has no dark proximal edge. The underside of its hindwing has much extended white markings. Röber proposes the name eros for this form. In Armenia, A. gruneri inhabits semi-deserts, juniper woodlands, and arid mountain steppes, at elevations ranging from 400 to approximately 2000 m above sea level.
