Haris A.: Second contribution to the sawflies of Belső Somogy
56 Natura Somogyiiínsis Periclista (Periclista) lineolata (Klug, 1816): In Hungary, it is known from Simontomya, Zirc, Cekeháza and Balk. It is also known from Cifáre (Csiffár), Ihelník, Ivano-Frankivska obi., Ukrainian Carpaths, Podcetrtek and Bílé Karpaty PLA: NNR Ceretoryje, NR Hute. Rhadinoceraea (Rhadinoceraea) micans (Klug, 1816): Captured again in this area. We dicussed it’s distribution in Haris, 2012. Dineura virididorsata (Retzius, 1783): Fig. 3. Extremely rare in the Carpathian Basin. It is known only from Bátorligeti láp and Nagyszeben (Sibiu). Pristiphora (Gymnonychus) abbreviata (Hartig, 1837): Although, its hostplants (Pyrus and Malus spp.) are common, this species is still rare. Known places of capture are Ujszentmargita and Nagykovácsi. It was also reported from Brebenyeszkul, Ukraine. Evaluation of the sampling sites The investigated area is clearly separated into core and marginal areas. The core area involves the sand-dunes consist of acidic sand. In some spots, these sand dunes are covered by clay. In deeper areas, where this clay is accumulated between dunes, it prevents the infdtration of the water to the deeper layers and supports wetlands, moors and even lakes (Fig. 4). The sand dunes are dominantly covered with Hornbeam, Turkey oak and Sessile oak forests (Querceto robori-cerris carpinetosum and Quercetum robori-cerris pteridieto- sum) Ferns are the dominant underbrush of these dry areas (Fig. 5), which consists mainly Pteridium aquilinum (Bracken), Athyrium fdix-femina (Lady fem) and Dryopteris filix-mas (Male Fem). In these forests birch (Fig. 6) and pine spots makes the vegetation more diverse. In the wet areas, the Alder vegetation is dominant. In the marginal area, the sand dunes are not present, the soil is harder, generally brown earths (cambisol) holding various vegetations: oak forests (Quercus cerris and Quercus petrea) with lime trees (Tilia tomentosa), wet meadows, creek willow vegetation. The marginal area holds the richest sawfly fauna, however, in these spots, dominantly common, ferquent and sometimes sporadic species were captured. Only 4 rare species were collected in these sites (mostly in Vése: Csöpröndi forest) of the 20 rare species. The investigation is very important of these sampling sites to get complete picture on the sawfly fauna, however, the most valuable faunistic elements restricted to certain spots of the core area. The richest sampling sites of the marginal area are: Bolhás: Hókamalom: Fishing pond; Somogyszob: marshy meadow at Segesd side of the village and Vése, Csöpröndi forest. In interesting way, 70 percent of the rare faunistic elements were captured in 4 sampling sites of the investigated 31 sampling sites only (!) in 2012 and 2017, these are: Berzence: Filagoria, Szenta: Felső-Gyóta forest, Tarany: Kettős-tó forest (Fig. 1) and Kaszó: Kanizsaberek (only the small Northern part). The most valuable parts of Szenta: Felső-Gyóta forest,where 1 specimen of Blasticotomafiliceti Klug, 1834 and 1 specimen of Heptamelus ochroleucus (Stephens, 1835) were captured in 2012, was clear cut probably 1 or 2 years later (Fig. 7). The other 21 sampling sites dominantly in the core area but also in the marginal areas resulted only few specimens of few (mostly lower than 10) species. Usually, there is a second but definitely smaller peak of sawflies in the end of July and early August (dominantly Arge, Athalia and Tenthredo spp.). In interesting way, in this aspect of the year, we found only 2 specimens of Athalia rosae (Linné, 1758) and 2 specimens of Arge melanochra (Gmelin, 1790), only at Hókamalom: Fishing pond.
