It is most striking to observe the significant expansion of species requiring larger quantity of moisture, which earlier had been recorded mostly from the western border and from the Northern Mountains. These are living on birch, alder or in the underwood of wet forests: Coeno- tephria sagittate L., Calocalpe undulata L., Leucodonta bicoloria Den, et Schiff., Larentia clavaria Haw., Dysstroma truncata Hufn., Hydrlomena furcata Thnbg., Anaplectoides prasina L., Diarsia brunnea Den. et Schiff. The area of some "Sibylla-type" species (VARGA 1964) also increased, e.g.: Aplasta ononaria Fuessl., Zanclognatha tenuialis Rbl., Pechipogo gryphalis H.-Sch., etc. In contrast with the previous species the thermophilous ones are on a gradual decrease. This contrasting trend in the change of areae may be due to the wet and rather cool summer of the past years. In the light of the new data I think it probable, that the fauna of the biggest part of the South Transdanubia, especially the afforested flat and hilly regions, is in direct connection with the fauna of the Praenoricum (the foot of Alps). The optimum life conditions of several hereunder listed species and others too are given in the rather wet and cool West Transdanubia. Thus, favourable weather conditions for these species give the possibility to extend their area and settling there temporarily. The presently observed faunal shift thus gives a partial explanation to many disputes over "unacceptable" faunal data some of them lasting for decades or for 100-150 years (cf. KOVÁCS 1958). Collected species and their localities In listing the species I follow my prevous system (the specific names have only been modified in a few times). The specimens have been deposited in the Lepidoptera collection of the Janus Pannonius Museum, Pécs, though some special specimens in the Hungarian Natural History Museum, Budapest. The material was wholly identified by me with some help from A. VOJNITS and L. RONKAY (

Eupithecia and Apamea species). The abbreviations of the localities are given under the map.
