be seen in the vicinity of Fraxinus, Salix, Populus and Prunus basking in sunny patches along forest tracks. Oviposting occurs from June to late August. Protected fauna. Status in the Bakony: 3/2. Polygonia I-album (ESPER, 1781) False Comma (Map 15, Item 54) A Eurasian species recorded in the region up until forty years ago but now believed to be extinct. Records show a single generation flew in June and July. The Farkas sisters were reported to have collected specimens in Herend's Fasor Park. In 1957 one specimen was captured by András Rohonyi in the Séd Valley, West of Veszprém. These localities have experienced many changes in past decades undoubtedly accounting for the species' disappearance. Protected fauna. Status in the Bakony: 0. Euphydryas maturna (LINNAEUS, 1758) Scarce Fritillary (Map 16, Item 56) A very local species in the region seen on the wing from the middle of May until the end of July. Consequential to the butterflies two year life cycle its occurrence can be sporadic, occasionally abundant. Mixed deciduous woodland in close proximity to streams and wet meadows seems to be the preferred habitat for this moisture loving species. The first Bakony records date back to 1962 when the butterfly was reported from the Rakottyás Valley, Herend. More recently it has been recorded from several new localities. One of the best localities is along the Vöröspataki road, Márké but even here it can be rare in some years. The butterfly and its habitats need to be fully protected from the ever present threat of forest mismanagement. Protected. Status in the Bakony: 3. Euphydryas aurinia (ROTTEMBURG, 1775) Marsh Fritillary (Map 16, Item 57) This species is widespread throughout the Palaearctic region but its occurrence in Hungary, as in many other European countries, is local and restricted to specific habitats. A dry from of E. aurinia occurs throughout much of the central 'strip' of the Bakony from Mt. Kab to Marko in the Southern Bakony and can be found commonly in May flying over South facing hillsides. In recent years it has been recorded further North of the Veszprém-Ajka breakline. Increase in populations may be attributed to the butterfly's ability to adapt to new surroundings. E. aurinia's hostplants in these dry areas are species of Plantago whereas Succisa pratensis is preferred by the marsh ecoform that inhabits the threatened wetland and meadows habitats in the vicinity of Uzsa, the Tapolca Basin and the Széki forest. During the last 10-12 years populations from these marshy areas have suffered from overcollecting and some protection is needed if these isolated colonies are to survive. More research is needed on E. aurinia in the region to determine whether the two ecoforms afford subspecific rank. Protected fauna. Status in the Bakony: dry form 4; marsh form 2.
