Maniola lupinus (COSTA, 1836) Oriental Meadow Brown (Map 10, Item 35) A Mediterranean species found flying in a single brood during mid summer. There have been no records for the past 15 years and this species is now believed to be extinct in the region. It was last recorded at Fenydfd in 1979 by László Rézbányai who captured a few specimens flying in a Northerly direction over forest tracks towards Bakonytamási. Protected. Status in the Bakony: 1/0. Pyronia tithonus (LINNAEUS, 1771) Gatekeeper (Map 10, Item 36) A rare species of the Transdanubian Massif found flying at the end of July until early September. The only place it regularly occurs is on the slopes of Mt. Szilvádi where during some years it flies in large numbers over Juniperus bushes in an isolated sandy area near Salföld. Weaker populations have also been recorded from Vállus, Káptalantóti and the Tihany Peninsular. There is some threat from overcollecting in these extremely local colonies. Not protected. Status in the Bakony: 3/2. IV. Family: NYMPHALIDAE Apatura iris (LINNAEUS, 1758) Purple Emperor (Map 11, Item 40) A Eurasian species found flying in shady deciduous woodland areas in the Northern Bakony. Males first appear on the wing in late June while females emerge a little later and can still be on the wing in mid August. During the last two decades this species has become increasingly rare and has disappeared from many of its former localities (Mt. Kab, Csinger Valley and the Szentgál Mis.). This is probably owing to the loss of many Populus and Salix trees in the region. In the Northern Bakony the butterfly has been recorded from Kisldd, Csalános Valley, Csehbánya, the Upper and Central Hajags and in the environs of Herend. Up until recently many of these areas were under the direction of Russian troops, and their army vehicles caused much damage to this region. Since the evacuation of all troops the faunistically rich Southern slopes and valleys of the Northern Bakony have started to recover and butterfly numbers have increased. Protected fauna. Status in the Bakony: 3. Apatura ilia (DENIS et SCHIFFERMÜLLER, 1775) Lesser Purple Emperor (Map 11, Item 41) Although this species is uncommon in the Bakony its appearance can be sporadic it can often be found more commonly than A. iris in the Balaton Highlands. It is single brooded in the region and flies from the end of June to mid August. A. ilia can be encountered in many places including deciduous forests, meadows, along damp watercourses and in private gardens and parks wherever its foodplant is to be found. The species is often seen feeding on animal faeces, decaying fish and bird excrement. Occasionally small numbers of males gather around wet patches of earth extracting mineral salts from the soil. Variations are extremely rare. The author captured one specimen of ab. eos ROSSI in Stone Pass, Kőszoros near Hárskút. Protected fauna. Status in the Bakony: 3
