Spiders of the genus Dysdera (Dysderidae) are ground dwellers characteristic of xerothermic forests of the Mediterranean and adjacent areas.
Habitat.--In the Czech Republic and Hungary this species occurs in xerothermic forests on slopes (e.g., plant communities Carpinion and Quercion pubescenti petraeae), in bushes (e.g., Berberidion) and in the shaded parts of rocky steppes (e.g., Festucion valesiacae).
It occurs on bed-rocks rich in minerals within xerothermic natural (Quercus spp., Carpinus betulus, rarely Fagus sylvatica) or planted forests (e.g., Pinus sp.).
Habitat.--Sexual populations occur in xerothermic forests (Quercus spp., Carpinus betulus, monocultures) on bed-rocks rich in minerals.
Habitat.--Dysdera adriatica occurs in various xerothermic forests and shrubland, mainly with dominant Carpinus betulus, Fagus sylvatica, Quercus cerris or Pinus nigra.
Habitat.--Dysdera longirostris occurs in various xerothermic forests and shrublands, often semirural ones, mainly with dominant Carpinus betulus, Fagus sylvatica, Quercus sp., or Pinus sp.
