Black lace-weaver — size comparison — facts and sources

The black lace-weaver inhabits wall crevices, cellars and spaces beneath stones or dead wood. It occurs in Europe and other temperate parts of the Northern Hemisphere. A subdued pale pattern is often visible on its abdomen.

In and before its hiding place it builds a funnel-shaped web with a tubular retreat. Capture threads bear fine fibres that help retain prey. Freshly made silk may have a bluish sheen. It works most actively at night, when it is easier to see at the retreat entrance.

Adult females are larger than males. Distinguishing it from other lace-weavers requires careful examination of structure, as lighting strongly affects the visibility of its dark pattern.
