DR. SZEŐKE KÁLMÁN - SZEŐKE LÁSZLÓ - NYIRŐ MIKLÓS: Results of the investigations on the Lepidoptera fauna of the eastern Bakony MTS
/in coll. HNHM Budapest/. New localities from the Eastern Bakony Mts. are the Barok-völgy and Fajdas-hegy. Goenocalpe lapidata HBN. A Holo-Ponto-Mediterranean element feeding on - by literature data - Clematis spp. It was known from Hungary for a long time only from the vicinity of Budapest /Budakeszi, Budaőrs, Hűvösvölgy, Csiki-hegyek, Hársbokor-he gy, Érd/ recently was discovered in the Bükk Mts: Várkút, Sikfőkút, Csanyik /GYULAI-UHERKOVICHVARGA 1974/, Mátra Mts: Gyöngyös, /in coll HNHM Budapest/ Pipis-hegy /JABLONKAI 1974/ and in Zemplén Mts: Rostallő /RONKAY-SZABÓKY 1981/. Two specimens were found in the Eastern Bakony Mts on the Fajdas-hegy in 8.X. 1983. Chersotis rectangula DEN. et SCHIFF. A monocentric Ponto-Mediterrane an species inhabiting rocky slopes and grasslands. It was recorded from Hungary from the Hungarian Middle Mountains, there are several localities but the individual numbers are very low. The known localities are the follows: Pannonhalma, SUmeg-Uzsa, Sukoró, Nadap, Csákvár, Várgesztes, Budapest, Pilisszántó, Esztergom, Pomáz, Isaszeg, Szécaény, Mátraszentlászló, Mátraháza. Bükk, Zemplén. Mts Recently was discovered in the Bakony Mts. /Fenyőfő, RÉZBÁNYÁI 1973» Ráktanya, RÉZBÁNYAI 1979a/ and in the Tapolca Basin /Hegyesd-Péterhegy, leg. T. Vers/. We have collected in the Eastern Bakony Mts. /Fajdas-hegy/ 8 specimens in 4.IX. 1984. The collecting data are show the imagos emerge mostly in June, and, after a short flying period - similarly to the Rhyacia species - they aestivate the hot and dry summer period. They come from their resting sitesat the end of the summer, and lav eggs, the small larvae go to overwinter. Consequently, the specimens collected in early summer are fresh while the late summer and early autumn specimens usually in poor conditions. Chersotis margaritacea VILL. An Euro-Siberian species distributed locally in the southern and central parts of Europe. Previous data from Hungary were only from the Bükk Mts. and the vicinity of Budapest /KOVÁCS 1953-56/. In the last ten years it was found in Aggtelek /GYULAI I. - GYULAI P. - UHERKOVICH - VARGA 1979/, Mátra Mts /JABLONKAI 1974/, Pilis Mts /SZEŐKE 1983/. On the Fajdas-hegy 7 specimens were collected in 1.IX. 1984, the occurrence of the species in the Eastern Bakony Mts. - as the ecological conditions are given there - is not surprising. Chersotis fimbriola ESP. A xeromontane species distributed from Spain te Iran /VARGA 1963/ inhabiting carstic and dolomite places • larvae feed mostly on the flowers of Pulsatilla species. Characteristic to its smell, usually isolated habitats. It occurs in Hungary only in the Budai-Mts. /KOVÁCS 1953/, Vértes Mts. /SZEŐKE 1983/, Gerecse Mts. /leg.Herczig/ , Eastern Bakony Mts. /NYIRO 1965, FAZEKAS 1980/, Keszthely Mts. /leg. Herczig/ and in the Aggtelek Carstic Mts. /VARGA 1963/. The imagos in their flying period /Middle of June-middle of July/ feeds on flowers of some Compositae species in early evening, they can be found by handlamps very easily, while they attracted by artificial light in significan tly lower numbers. In daytime they rest under stones or at the surface, though sometimes specimens also can be found in daytime feeding on flowers /FAZEKAS 1980/. This species has no summer aestivation, the specimens after some days flying already usually damaged. The intensive erosion of the wing scales - while the specimens get a special, somewhat reddish shade - very probably connected with their resting strategy. As the populations are well isolated from each other, the morphological variability of them might be originated from their different genetic characteristics, consequently the revision of this species is needed. The populations from different localities from Transdanubia are - beside their differential features - more or less similar to each other. From this reason, before the revision, we consider them to be identical with the nominate race, while the populations living in NE Hungary belong very probably to an another subspecies. This species was found in the Eastern Bakony Mts. at Inota and Várpalota, in dry rocky swards.
