Haris, A.: Sawflies of Southern part of Somogy county (Hymenoptera: Symphyta).

Abstract: 100 species of 683 specimens were collected in the Duna-Dráva National Park and the adjacent territory: Csokonyavisonta Wooded Pasture. Caliroa cothurnata (Serville, 1823) is new record for Hungary and for the Carpathian Basin. Rare species are: Xyela (Xyela) juhi (Brébisson, 1818), Monoctenus juniperi (Linné, 1758), Dolerus (Poodolerus) blanki Liston, 1995 and Euura fuscomaculata (Förster, 1854).

Introduction

This year, the Southern part of Somogy County (Fig. 1) was investigated, namely the Somogy part of Danube-Dráva National Park and the protected wooded pasture at Csokonyavisonta. The sampling places are restricted to 3 different areas. These are the Protected Wooded pasture at Csokonyavisonta, Juniper woodlands at Darány and the floodplain of River Dráva at Vízvár.

Csokonyavisonta Protected Wooded Pasture

This wooded pasture (Figs. 2, 5 and 6) was a result of human activity, namely the traditional extensive livestock breeding (cattle and pigs) in the last centuries.

The altitude of the area varies between 120-140 m. Within this small area, there are high diversity of habitats typical for Somogy county from the sand dunes till the wet and swampy depressions holding alder-moors.

Among the forest associations there are hornbeam-oak, Turkey oak forests, alder bogs and also gallery forests.

By giving up grazing, the proportion of open areas has been steadily declining. Maintaining the remaining grasslands is an important task for nature conservation.

Juniper woodland at Darány

Juniper woodland (Figs. 3 and 4) is also a result of pasture farming: grazing animals avoided prickly junipers therefore very special and unique habitat is formed in this area during the last centuries. For our days, only two larger spots remained, the other parts were replaced by forest, when grazing was abandoned. These spots are actually sand dunes covered by sporadic Juniper groups.
