Distribution

Habitat

Principally Quercus-Carpinus and Fagus forests in central and western parts of Slovakia. According to Stašiov (2002, 2005), suitable sites were Quercus-Carpinus forest litter with low humus and carbon content, high nitrogen content and maximum degree of saturation capacity of the soil and litter layers; some of the forests were relatively young, with smaller trees (40–60 yrs), but at least one well-populated stand was 80–100 years old. In Fagus stands there was more activity in litter of relatively low pH. Trees listed from the sampling sites were Quercus petraea , Q. cerris , Q. dalechampii , Q. virgiliana , Carpinus betulus , Fagus sylvatica , Fraxinus excelsior , Tilia cordata , Acer campestre , Picea abies , Abies sp. Site records indicate a vertical distribution between 200 and 930 m in the area studied, with Quercus forest lower down, increasingly mixed with Fagus going higher up and then replaced by mainly montane Fagus forests, some ( Fagetum dealpinum) on dry, steep calcareous slopes. True Central European xerothermic mixed Quercus woodland on sunny, base-rich soils too dry for Fagus includes Lithospermo- Quercetum, another quoted habitat. Julus curvicornis was also recorded from mixed Fagus , Abies and Picea ( Fagetum Abietino-piceosum) which is situated above 850 m.
