326 EDIT VADKERTI Fig. 1. Location of Isophya costata (О) and I. modestior (X) on UTM grid map of South-Baranya-Hills (South-Hungary, Transdanubian region). I. modestior was found in two habitats: in moist forest edges and in forested areas with spontaneous bushy growth. In Mecsek Hills and Villányi Hills there are no incidences of the species in these habitats (VADKERTI et al. 2003), but there were in the next seven habitats: meadows with false oat-grassland in mountains and hilly regions, grassy steppe slopes and wooded steppe meadows, stabilized meso-xeric clearing meadows, grassland and dry high weed associaBORHIDI, A., SÁNTA, A. 1999: Vörös Könyv 2.

It seems that the Isophya fauna of Mecsek Hills and Villány Hills are different in many aspects from SouthBaranya-Hills, which is located between them. On the one hand, only two species were found from the expected four. On the other hand, there are variances in the habitats of the species. Probably the differences originate primarily from the divergence of the relief, climate and the vegetation. VADKERTI et al. (2003) found /. modestior and /. modesta in 72.3% of habitats Mecsek Hills and Villány Hills witch are characteristic in this area but are absent from the studied area. /. brevipennis was found in Mecsek Hills and Villány Hills in moist, mesic grasslands and forest edge ecotones. This category of habitat occurred in the studied area but in grassland the sweeping-net method was not effective and it is not useable in bushy habitats. Due to the nocturnal activity of Isophya species (SZÖVÉNYI er al. 2001), acoustic detection could not be successful during daytime, so the conditions of sampling could have influenced the results. As the result of the research it can be claimed that the Mecsek Hills, Villány Hills and South-Baranya-Hills is the region with the greatest number of localities of Isophya species in Hungary.
