Neptis aceris (LEPECHIN, 1768) ssp. sappho PALLAS Common Glider (Map 12, Item 42) This handsome Glider is one of the Balcony's most endangered butterflies. A bivoltine species usually encountered in May/June and July/August in one or two isolated colonies in the region (Balatonarács, Koloska Valley, Márka and the Menyeke Forest). It has a very delicate flight pattern and is only ever seen on the wing in warm, calm weather conditions. Because of this inadequacy colonies remain isolated and endangered. There is some confusion over the butterfly's nomenclature status as to whether Lepechin's description preceded those of both Pallas 1771 and Esper 1783. Protected. Status in the Bakony: 2. Neptis rivularis (SCOPOLI, 1763) Hungarian Glider (Map 12, Item 43) There have been no records for this Eurosiberian species over the last decade. A small colony existed on Mt. Kab during the 1970's but when its foodplant Spiraea salicifolia was wiped out by a forestry program the species became extinct. The only known specimens from the Bakony region are kept in the BTM Collection. Protected. Status in the Bakony: 1/0. Limentis reducta STAUDINGER, 1901 Southern White Admiral (Map 13, Item 45) A recent addition to the Bakony region first observed near Csopak in the upper section of the Nosztori-Valley by the German lepidopterist Walter Baltruweit. Its hostplant Lonicera xylosteum grows plentifully along shady overgrown roadside habitats in this area of mixed, chiefly Quercus forest. There have been no sightings over the last two years and there is some concern relating to the disruption caused by weekend visitors. Protected. Status in the Bakony 1. Nymphalis xanthomelas (DENIS et SCHIFFERMÜLLER, 1775) Yellow-legged Tortoiseshell (Map 14, Item 50) A Palaearctic species only found on the Hungarian Western border and now sadly extinct in the Bakony region. Small colonies existed in the Herend district up until 1957 (specimens survive in the collection of Agnes and Sarolta Farkas). In previous decades when Salix trees were plentiful it is presumed that this species had a wider distribution. Post hibernating specimens are on the wing from June until August. Protected fauna. Status in the Bakony: 0. Nymphalis polychloros (LINNAEUS, 1758) Large Tortoiseshell (Map 14, Item 51) This species was once common in nearly all the Bakony region. It bred prolifically, its numbers increasing and spreading throughout the Balaton Highlands and Séd Valleys. Butterflies were commonly seen in parks, gardens and along roadside verges. Unfortunately in the past decade its numbers have plummeted and many suitable habitats where Salix and Populus once grew have been destroyed. Increased road traffic more frequently disturbs butterflies along what were once quiet forest tracks. Post hibernating specimens can usually be seen during the first warm days of March. Butterflies prefer to stay out of the shade and can often
