but belonging to different species groups of the same genus (I) P. ariana (MOORE, 1865) {stoliczkanus group) (Figs 9-10), which lives in high altitude habitats in the Western Himalayas and (2) the Common Blue, P. icarus (icarus group), which has a Transpalaearctic distribution (Figs 11-12). For studies by microscopy and for physical measurements we used museum material. The specimens examined are deposited in the Lepidoptera collection of the Hungarian Natural History Museum. For scale nanostructure investigations half of the forewing was cut as dry sample, fixed with double-sided carbon tape and gold coated for scanning electron microscopy. High-resolution observations were carried out using a LEO FESEM scanning electron microscope. Figs 3-6. Male individuals of Polyommatus taxa investigated by spectroscopy, showing dorsal surfaces scanning electron micrographs showing structural blue colour generating cover scales with pepper-pot structures: 3 = P. eros (OCHSENHEIMER, 1808) individual, 4 = P. eros scale, S- P. eroides (FRIVALDSZKY, 1835) individual, 6 = P. eroides scale
