The spider is very wide and flattened, with a leathery skin. Its color ranges from red brown and grey brown to black with a dark, yellowish to yellow-greenish leaf-like fleckled marking on its opisthosoma, where small dents are visible. These are the onsets of muscles that flatten the abdomen.
The spider hides during the day outside of buildings in wall crevices, or under loose bark. They are very common in Central Europe; females occur all year long, while males appear mostly during summer.
